Part 2. Description
•Designed for Thorlabs' Ø5.6 mm (TO-46) and Ø9 mm (TO-18) Pigtailed Laser
Diodes, Single Mode, Polarization Maintaining, or Multimode
•TEC Element Prolongs LD Life and Stabilizes Output Power and Wavelength
•Clamshell Design Eliminates Thermal Gradients cross Diode
•Bias-T dapter for RF Modulation of Laser Current >1 GHz
Thorlabs' LM9LP is an LD and TEC mount designed for use with all of our 3- and 4-pin
pigtailed diodes1. The compact housing protects the pigtail from physical damage, while
also offering excellent thermal characteristics. Two 1/4" through holes can be used for
securing the mount to an optical table with 1/4"-20 or M6 cap screws.
When operating a pigtailed laser diode, temperature control is highly recommended to
stabilize the laser's power and wavelength, while also prolonging the life of the laser.
Typical laser diode mounts rely on contact between the diode and the mount's cold plate
for heat transfer. Pigtailed laser diodes are often recessed in the pigtail's housing, offering
poor contact with the cold plate of standard laser diode mounts. The LM9LP, however, is
specifically designed for operating pigtailed laser diodes. Its clamshell design reduces
thermal gradients across the diode, while its cold block cradles the pigtail housing for
excellent contact and heat transfer. Performance can be further improved by using
thermal grease around the pigtail package within the clamshell.
DB9 connections interface with all of Thorlabs' LD Current Controllers and TEC
Controllers. n SM connector allows access to a Bias-T circuit for RF modulation of
the laser's drive current (200 kHz to >1 GHz). For modulation below 200 kHz, current
should be modulated through the laser diode controller. remote interlock jack is
provided for the connection of safety devices such as shutters and warning signs.

•The four sockets of the laser diode connector are through hole type sockets.
•The laser connector may require an S7060R socket to be used when connecting a
laser diode with short leads. This adapter is included with Thorlabs pigtails.
•Most laser diodes are three pins with the case tied to one of the laser pins and also
to one of the photodiode pins. The other laser and photodiode pin will be isolated
from the case. The LM9LP was designed to operate the laser case at ground
potential therefore this common pin will be inserted into either of the holes marked
‘G’ below. Insert the isolated laser pin in the position marked LD. The isolated
photodiode should now be in the position marked PD.
Figure 3: Laser Diode Socket
•Thread the two 2-56 socket head screws into the pigtail flange, securing it to the
mounting flange. Next, replace the copper cold plate cover and tighten its two 2-56
socket head screws. Lastly, reattach the cover plate using the two 2-56 socket head
screws.

3.2. Special Note or 4-pin Laser Diodes
The LM9LP also supports 4-pin laser diodes. Insert the laser into the 4-pin socket and
note which laser pin is in the 12 o’clock position (laser anode or cathode). lso, note
which photodiode pin is in the 6 o’clock position (anode or cathode). The mount will tie
the laser and photodiode pins located at 9 o’clock and 3 o’clock together and also to
ground. By noting which polarity pins are inserted in the socket, you can convert the 4-
pin layout to one of the 3-pin layouts in Figure 2 above. Set the LD and PD polarity
switches accordingly.
Laser diodes with pin style F are not compatible with this mount. The pins are oriented
across from each other and will not align properly in the mount.
Figure 4: Pin Style F
3.3. Special Note or Laser Diodes without a Monitor Photodiode
Laser diodes without a monitor photodiode will also work with the LM9LP. The laser
diode pins must be positioned between the LD and G positions. Some 2 pin packages will
not align with the laser diode socket, but 3 pin versions can be mounted similar to typical
laser diodes with photodiodes.

3.4. Laser Diode Current Controller Connection
Using the Thorlabs LDC/ITC Series Laser Controllers:
• The LM9LP is compatible with all Thorlabs LDC LD controllers and ITC series
combination controllers (LD and TEC). ppropriate cables with DB9 connectors
are included with Thorlabs controllers and ensure that the controllers cannot be
connected incorrectly. dditionally, these controllers have built-in protection
circuitry that protects the laser when not in use.
• The nomenclature for the Laser Diode polarity switch on the LDC40xx and
ITC40xx drivers and the LM9LP are consistent with each other. For example, if
the laser polarity on the driver is set to “ G” (anode grounded), then the LD
polarity switch on the LM9LP should also be set to G, and so on.
• The nomenclature for the Photo Diode polarity switch on the LDC40xx/80xx and
ITC series drivers and the LM9LP is as follows: The photodiode polarity switch on
the LM9LP must always be set to “CG”. The photodiode polarity should be set
with the internal Laser controller switch only. For more information on how to set
Polarity settings on the Laser controller, please refer to the appropriate Laser
Controller manual.

3.7. TEC Lockout and Ground Jumpers
Two jumpers, JMP1 and JMP2, are located under the cover on the main PCB assembly.
JMP1 allows you to enable or bypass the TEC Lockout feature. This feature, when
enabled, will prevent the laser diode from being turned on unless the TEC controller is
enabled. The unit is shipped from the factory with the TEC Lockout feature bypassed. To
enable the TEC Lockout, simply remove the cover of the unit and remove the blue
jumper from the JMP1 header. The jumper can be placed on one of the other header pins
for safe keeping.
n optional ground jumper is also provided to allow connecting the system ground node
(common to the “G” pins of the laser diode connector) to the metal housing of the unit,
which is also connected to the shields of the LD and TEC input cables. Care should be
taken when using this connection as unwanted ground loops may be formed. The unit is
shipped from the factory with JMP2 disconnected. To close this connection, remove the
cover of the unit and place the blue jumper onto both pins of the JMP2 header.

Part 4. Operation
4.1. General
Once the laser is mounted in the LM9LP and a Laser Diode Current Controller and TEC
Controller are connected, the device is ready to operate. Please refer to the operating
instructions for the laser and temperature controller for specific operating instructions.
When operating at low temperatures in high humidity climates, the laser mount may
develop internal condensation. If this occurs, turn the laser off, open the case, and allow
the mount to dry off completely before reusing.
4.2. RF Modulation
The LM9LP has an RF input for modulating the laser with an external RF source from
200 kHz to beyond 1 GHz. This is a 50 Ω input that is C-coupled directly to the laser
through the Bias-T network. To calculate the desired RF power to modulate the laser,
determine the amount of modulating current needed from the laser manufacturer’s data
sheets and use the following calculations:
   
It is strongly recommended that you start off conservatively by a factor of 10 below the
calculated modulating voltage and slowly bring the RF power up until the desired depth
of modulation is reached.
Use the laser controller to establish the DC operating point of the laser.
WARNING
T e RF input is directly coupled to t e laser. Any excessive transients
or noise will be coupled into t e laser and may cause t e laser to be
overdriven. Also, t e laser can be easily overdriven if excessive RF
power is applied to t is input. Use t e RF modulation input wit care
to avoid damaging your laser.

20913-D02 Rev F, June 23, 2014 Page 13 www.thorlabs.com
4.3. Status and Interlocks
This unit is equipped with two interlock circuits and an LED that indicates if the laser
diode is enabled. ll three circuits are designed to interface with Thorlabs’ laser and TEC
controllers with no external circuitry.
• If third-party controllers are used to drive the laser diode or TEC elements, then
only the LD on indicator can be used. To prevent damage to the Status and
Interlock circuits, the following external connections should be followed:
• Install the shorting device into the REMOTE INTRLK connector that was shipped
with the LM9LP.
• Install the TEC LOCKOUT bypass jumper into JMP1 inside the LM9LP case (see
3.7).
• Connect a resistor to LD Interface DB9 Pin 1 appropriately sized to limit the
current into Pin 1 to between 5 and 10 m .
• The “driver” side of this resistor should be connected to a DC signal that, when
high, indicates that the laser diode is being overdriven.
• If you have any questions regarding these connections, please feel free to contact
an engineer at Thorlabs for clarification.
If you wish to make full use of all of the Status and Interlock features with your third-
party drivers, please contact Thorlabs and an engineer will help you determine if this is
possible and how to implement these features.
4.4. Maintaining the LM9LP
There are no serviceable parts in the LM9LP. The housing may be cleaned by wiping
with a soft, damp cloth. If you suspect a problem with your LM9LP, please call Thorlabs
and an engineer will be happy to assist you.

20913-D02 Rev F, June 23, 2014 Page 14 www.thorlabs.com
Part 5. Making Safety nterlock Connections
The LM9LP is equipped with a Remote Interlock connector located on the side panel. In
order to enable the laser source, a short circuit must be applied across the terminals of the
Remote Interlock Connector. In practice this connection is made available to allow the
user to connect a remote actuated switch to the connector (i.e., an open door indicator).
The switch, which must be normally open, has to be closed in order for the unit to be
enabled. Once the switch is in an open state, the laser diode must automatically shut
down.
ll units shipped from Thorlabs are configured with a shorting device installed in the
interlock connector. If you are not going to use this feature, then you can leave the
shorting device installed and the unit will operate normally as described in the procedures
in this manual. If you wish to make use of the interlock feature, you will need to acquire
the appropriate connector mate and wire it to your remote interlock switch. Next, remove
the shorting device by unscrewing it from the input and install the connector into the
interlock input.
The interlock input only accepts a 2.5 mm mono phono jack. This connector is readily
available at most electronics stores (Radio Shack, Digikey, Mouser, llied, etc.).
The electrical specifications for the interlock input are as follows:
Specification Value
Type of Mating Connector 2.5 mm Mono Phono Jack
Open Circuit Voltage +5 VDC with Respect to Chassis Ground
S ort Circuit Current ~8 m DC
Connector Polarity Tip is +5 V, Barrel is Ground

Part 6. Troubleshooting
If you are using Thorlabs’ Laser and TEC controllers with your LM9LP:
Problem Fix
Laser Driver will not Enable Make sure the Remote Interlock is closed. Check the laser diode
polarity and make sure the polarity switches on the mount are
set correctly.
Remote interlock is open Make sure that either the shorting device is installed in the
REMOTE INTRLK connector on the side of the LM9LP. If you
have a remote interlock switch connected to this REMOTE
INTRLK connector, it must be in a closed position.
TEC lockout circuit is active and
t e TED Series TEC controller is
not enabled
To determine if you have selected the TEC Lockout circuit to be
active, refer to 3.7 and Figure 7. If it is selected, then the TED
Series TEC controller must be enabled first before the LDC
Series laser controller can be enabled.

RF modulation of the LM9LP can be accomplished in one of two ways. For low
frequencies (below ~200 kHz), the RF modulator should be connected to the LD
controller. Figure 8 shows the performance of Thorlabs’ LDC202C and ITC4005 when
used with the LM9LP and RF modulation. bove 200 kHz, the modulator should be
connected to the LM9LP’s SM connector. The mount has been tested up to
1 GHz, which is shown in Figure 9 below.
