INTUN Series Tunable Lasers Chapter 2: Description
740-TL1300-B-B Manual Intun TL1300-B Page 5
•SM1 Thread: The INTUN laser is equipped with internal SM1 threading on the optical exit port, thus
enabling seamless integration into a SM1 lens tube system.
2.4. Features
The INTUN laser offers continuously tunable mode-hop-free operation. This system is controlled via a USB
interface. The USB port is treated by the host software as a serial com through virtual com port drivers (VCP).
The set of commands for the INTUN laser are based on the MSA standard for tunable lasers and includes
additional commands to improve functionality.
The INTUN laser series comes with a LabVIEWTM software package that enables the user to control the laser via
a computer. The software package contains a standalone graphical user interface (GUI) and drivers that can be
run from within LabVIEWTM. Dynamic link library drivers (DLL) are available upon request and enable driver
integration into a large number of programming languages.
•USB interface with extensive set of PC host software
•High-resolution wavelength tuning with modulation functions (coherence control)
•High-resolution optical power control with modulation functions
•Continuous and mode-hop-free sweep capability over entire wavelength range
•Robust design
•High-performance, single-mode, low noise spectral characteristics
oHigh spectral purity
oSignal to source spontaneous emission ratio
oSide mode suppression
2.5. Operating Elements
Figure 2 INTUN Laser Front Panel
The INTUN laser is switched on and off with a key and controlled by software optimized for a WindowsTM PC.
Please see Section 3.1 for information on software installation.

740-TL1300-B-B Manual Intun TL1300-B Page 6
•Modulation Input: Modulation input for analog optical power modulation. Maximum signal amplitude is
2 VP-P.
•Wavelength Output: Analog output signal representing the actual wavelength. The output amplifier is
0 to 4 V. The load should have an impedance of 10 kΩor higher.
•Power On: LED indicates main power on.
•Laser On: LED indicates laser optical power on.
•Modulation On: LED indicates Analog Dither enabled. The optical power can be modulated with the
modulation input BNC connector.
•System Error: LED indicates a fatal failure.
Figure 3 INTUN Laser Rear Panel
•USB: This is the communication interface to the host controller (WindowsTM PC). Use an A to type mini B
USB cable.
•Interlock: To enable laser output, the DB9 connector pin 1 and pin 2 must be connected. This feature
should be used to comply with safety requirements where applicable.

INTUN Series Tunable Lasers Chapter 3: Setup
740-TL1300-B-B Manual Intun TL1300-B Page 7
Chapter 3 Setup
3.1. Software Installation
See the INTUN-B software installation guide included in the host software CD package (right click the CD drive).
Figure 5 Software Installation
3.2. General Information about GUI
The GUI executable is a ready-to-use graphical user interface where all laser features can be controlled from
within five tabs. All of these features can also be controlled from within the control software (right click the CD
drive to access the installation and driver documentation- see Figure 5 above). See pages 10 to 14 for more
information.
•Main tab: Control wavelength and power; read the actual wavelength through a laser wavelength sensor.
•Parked tab: Tune the wavelength in three different modes: closed loop, step, and piezo/fine tuning,
features that allow both fast and ultra-high-resolution tuning.
•Sweep tab: Set a wavelength continuous mode-hop-free sweep between two different wavelengths with
a specific tuning speed. (0.02 to 100.00% of max tuning speed, see model-specific max tuning speed).
•Dither tab: Set digital dither to internally generate modulation signals for optical power (frequency and
depth) and wavelength (depth). Supports simultaneous modulation of both power and wavelength. Enable
analogue dither for external modulation control of optical power through front panel BNC connector.
•Status tab: Laser status; cleared when exiting the tab.
White controls and slides are adjustable (when not grayed out). Items on the GUI with yellow background or
yellow parts are read-only indicators.

INTUN Series Tunable Lasers Chapter 3: Setup
740-TL1300-B-B Manual Intun TL1300-B Page 8
3.3. Getting Started
After installation of the INTUN software, connect the unit following the steps below:
1) Connect the power supply adapter and USB cable.
2) Connect the interlock at the rear panel.
3) Turn on the INTUN laser (the system will be lasing at this point).
4) Start the INTUN GUI from the start menu.
5) Select the INTUN in the USB devices list.
6) A pop-up dialog will pause the GUI during the laser initiating process. The INTUN-B startup time is less
than one minute, after which the GUI is enabled.
7) The GUI will be initiated with current laser settings and ready to use.
NOTE
When the laser is started, the lasing will be activated during the start-up sequence and will remain
activated until you switch it off.
3.3.1. First-Time Operation
Once the INTUN laser and GUI are started, set power and wavelength with the knobs or enter values in white
digital controls.
If turned off/on or reset, the laser will go through the start-up sequence again, during which the GUI will be
paused for less than one minute (typically around 20 seconds).

2) Check the power on and system error LEDs.
3) Check the current limit GUI indicator.
4) Check the top display in the GUI Status tab for information.
5.2. Service
In order to be within optical specifications, it is recommended to do service after 5 x 107sweeps or one year,
whichever occurs first.
5.3. Warranty
Thorlabs warrants material and production of the INTUN TLS for a period of 12 months starting with the date of
shipment. Thorlabs will make the final determination as to the cause or existence of the defect and, at our
discretion, repair or replace the products that prove to be defective during the warranty period. Products replaced
under warranty will be warranted only for the balance of the warranty period of the originally supplied equipment.
Additionally, any purchased replacement parts, i.e. laser tubes, power supply modules, etc., are warranted for a
six-month (6) period.
Review the terms of your purchase and the date of shipment to determine the validity of your warranty claim.
Warranty claims should only be made for products that are within the terms of the warranty policy. However, out-
of-warranty items may be returned for evaluation at no charge.
Prior to returning any unit for repair or evaluation, please contact Thorlabs either by phone at
[phone] or by fax at [phone] to obtain authorization to return the unit in the form of a Return
Authorization number. This number is valid for a set period of time; 30 days for domestic customers, 45 days for

INTUN Series Tunable Lasers Chapter 7: Regulatory
740-TL1300-B-B Manual Intun TL1300-B Page 20
Chapter 7 Regulatory
As required by the WEEE (Waste Electrical and Electronic Equipment Directive) of the European Community and
the corresponding national laws, Thorlabs offers all end users in the EC the possibility to return “end of life” units
without incurring disposal charges.
•This offer is valid for Thorlabs electrical and electronic equipment:
•Sold after August 13, 2005
•Marked correspondingly with the crossed out “wheelie bin” logo (see right)
•Sold to a company or institute within the EC
•Currently owned by a company or institute within the EC
•Still complete, not disassembled and not contaminated
As the WEEE directive applies to self-contained operational electrical and electronic products, this end of life take
back service does not refer to other Thorlabs products, such as:
•Pure OEM products, that means assemblies to be built into a unit by the user (e. g. OEM laser driver
cards)
•Components
•Mechanics and optics
•Left over parts of units disassembled by the user (PCB’s, housings etc.).
If you wish to return a Thorlabs unit for waste recovery, please contact Thorlabs or your nearest dealer for further
information.
7.1. Waste Treatment is Your Own Responsibility
If you do not return an “end of life” unit to Thorlabs, you must hand it to a company specialized in waste recovery.
Do not dispose of the unit in a litter bin or at a public waste disposal site.
7.2. Ecological Background
It is well known that WEEE pollutes the environment by releasing toxic products during decomposition. The aim of
the European RoHS directive is to reduce the content of toxic substances in electronic products in the future.
The intent of the WEEE directive is to enforce the recycling of WEEE. A controlled recycling of end of life products
will thereby avoid negative impacts on the environment.
