1 BOOSTIK HP Description
The Koheras BOOSTIK HP system is a Continuous Wave (CW) laser and amplifier
system. The system produces and amplifies infrared laser light that is ultra-bright and
near-diffraction-limited. The amplified light is then delivered through an armored fiber
to collimating optics for emission output.
The amplifier contains reliable, high-brightness diode lasers that pump a double-clad,
ErYb-doped or Yb-doped optical fiber. Microprocessor controlled electronics power
the diode lasers and control the fiber amplifier operation. A heat sink and fan provide
the necessary cooling for reliable operation. All components of the system are
housed in chassis that are both benchtop and rack mountable and include front panel
controls.
Optical output A BOOSTIK HP emits fundamentally transverse mode (TEM00) continuous wave
radiation in the 1064nm or 1550nm range. Optical power is continuously adjustable
from 3 to 15 W.
Amplifier
characteristics
With the amplifier used in a Koheras BOOSTIK HP system, the laser’s optical output is
defined by an ultra-narrow line width in the Hertz range and exceptionally low
frequency and intensity noise. These characteristics make the laser suitable for
applications such as quantum optics, computing and other phenomena like optical
trapping, optical lattice, Bose-Einstein condensate, atom interferometry, and
squeezing.
Note: Other applications for a BOOSTIK HP system include using it as a linear optics
pump source in conjunction with second harmonic and differential frequency genera-
tion, optical parameter oscillators, and laser-based metrology.
Integrated systems BOOSTIK HP system with Koheras ADJUSTIK
When integrated with a Koheras ADJUSTIK, the BOOSTIK HP system operates in a
master/slave configuration. A Koheras BOOSTIK amplifier (slave) is paired with a
Koheras ADJUSTIK laser (master). The Koheras ADJUSTIK functions as a seed laser
source, and when combined with the amplifier, the master device (the ADJUSTIK)
manages all the controls of the slave device (the BOOSTIK HP amplifier).

BOOSTIK HP Description
BOOSTIK HP Description 16
BOOSTIK HP system with Koheras ACOUSTIK
When the amplifier is integrated with a Koheras ACOUSTIK multi-wavelength system
it can be seeded by one of a range of ultra-low phase noise single-frequency laser
modules
1
: This gives high flexibility and freedom to select specific wavelengths and
power levels required for multiple discrete applications.
Warning: You must safely terminate the optical output of seed laser modules in-
serted in an ACOUSTIK rack which are not connected to a BOOSTIK HP amplifi-
er.

Wavelengths and power
BOOSTIK HP systems are specified by two models based on the Koheras seed type
used for its input; either E15 or X15 and Y10.

associated specifications.

Optical output
Optical output is Class 4 emission delivered through an output fiber to a collimator.
The collimator is the amplifier’s primary optical output.
Optical input
Optical input is received from a seed laser through an FC/APC connector.
The input to a BOOSTIK HP amplifier is designed to receive light from a CW seed
laser. The output of the seed can be frequency modulated within a range as specified
by the output from the Koheras BASIK modules listed in
Table 1 .

Caution: Only connect a seed laser source as specified in Table 1. Amplitude
modulated or pulsed input can result in extensive damage to the BOOSTIK
HP amplifier.
Caution: Do not connect a seed laser source with a wavelength beyond
the optical input wavelength range specified for your amplifier. Doing so may burn
the system components.
Caution: Do not connect a seed laser source with a power level that exceeds 50
mW. Doing so may burn the system components.
Power LED
This LED indicates when power is applied to the BOOSTIK HP amplifier – see
Table 2 .
Status LED
This LED indicates the status of the BOOSTIK HP amplifier – see Table 2 .
Emission LED
The emission LED indicates if emission is enabled – see Table 2 .
Table 2 Front panel LED conditions
Warning: When the emission LED is flashing or ON, dangerous laser emissions
are present. Take all proper safety precautions necessary. The Koheras BOOS-
TIK HP Safety, Handling and Regulatory Information document provides multiple
safety information that should be adhered to along with applicable regional safe-
ty regulations.
Rack mounting handles
Use the handles as grips when transporting the amplifier or mounting it in a 19 inch
equipment rack.
Rear panel Figure 4 shows the rear panel which includes multiple connectors, a ventilation
outlet, a switch controlled AC power connection, an address selector for the
communication bus, and a holder for the output collimator. Connectors include ports
for monitor, control signals, interlock, and connected accessories.

emission.
Blinking The interlock is open or interrupted by an error.

Press ( I ) to turn on the amplifier power and ( 0 ) to turn it off.
Cooling fan exhaust vent
To maintain the laser amplifier’s operating temperature, cool air is drawn into the
chassis from the bottom panel vent and system heated air is subsequently expelled
from the exhaust vent on the rear panel. During operation, ensure to keep the areas
in front of both vents clear of any obstructions that could block the free flow of air.
Collimator holder
A receptacle that secures the collimator in place when transporting or storing the
amplifier. DO NOT operate the amplifier when the collimator is placed in the holder.
External bus address selector
This is a rotary switch which sets an offset to the External bus communication
address. You can use the switch to set a bus address offset from 0x0 to 0xF. Devices
on the External bus must have a unique bus address. Without setting an offset, the
main module address for a standard BOOSTIK HP is 0x40 – see
“Setting the
External bus address” on page 34

External bus through
When operating without smart accessories, connect the included bus defeater to this
port. The bus defeater loops back the interlock, see –
“External bus cable and bus
defeater” on page 33
. Smart accessories can connect to the external bus for
communications, power and interlock signals. In the future, should accessories
become available, you can connect them to this port.
External bus input
Connect this to the seed laser of your BOOSTIK HP system; either an ADJUSTIK or
ACOUSTIK. The bus carries communication over RS-485 protocol and importantly,
the interlock signal from the seed laser.
MWarning: DO NOT BYPASS the interlock on system’s seed laser by jumping the
pins on the interlock connector. Laser regulations require that the interlock is
connected to a safety door switch. When the door switch circuit is open, the laser
is immediately disabled.
Note:
The Koheras BOOSTIK HP system has built-in safety relay and interlock fea-
tures to help ensure laser radiation is emitted only when it is expected and only when
predetermined conditions are met.
The remote interlock and remote stop features render the system inoperable when a
predefined condition occurs, such as the opening of a door. The internal safety relay
is analogous to a beam shutter. It interrupts drive current to the diode pump lasers,
and it is open each time the system is turned on. This means it will be impossible to
apply current to the diode pump lasers until you specifically take action to close the
circuit and reset the front panel keyswitch on the seed laser – see
“Connecting the
safety interlock” on page 31
.
External Feedback
Reserved for future use.
Emission ON/OFF
Reserved for future use.
Modulation Input
Reserved for future use.
Monitor output
FC/APC connector – emitting approximately 0.05% to 0.2% of the amplifier’s
main optical output power. Emission from the monitor output is classified as
CLASS 3B.
Optical outputs
The optical outputs for BOOSTIK HP systems are listed in Table 3. A diagram of
optical outputs and inputs is shown in Figure 5.
