T-Cube Laser Diode Driver
OUTPUT Potentiometer
- Used to set the output intensity (power) of the laser.
MODE Button
- Switches between CONSTANT POWER and CONSTANT
CURRENT modes - see Section 4.8.
LASER ON Button
- Turns the laser output ON and OFF. The LED is lit when the
laser is on.
OPEN LED
- Lit when the INTERLOCK is open - see Section 3.3.11 . Flashes
when the laser diode is open circuit.
POWER LED -
Lit when power is applied to the unit.
KEYSWITCH - Turns the laser output ON and OFF. The KEYSWITCH LED on the
GUI panel is lit green when the key switch is turned ON and red when the switch
is OFF - see Section 6.1.

Set Up Preparation
The following procedure assumes that t he laser diode is mo unted in a Th orlabs
LM14S2, LDM56, LDM90 or LDM21 diode mount. If this is not the case, care must be
taken to ensure that the laser diode is connected to the rear panel D-Type connector
with the correct polarity - refer to Section 3.3.4. for more details. A power meter and
suitable detector head are also required.
1) Insert the laser diode into the diode mount, taking care to observe the correct
orientation.
2) Set the switches on the diode mount to select the correct polarity (AG or CG) for
the diode being used.
3) Using cable CAB400, connect the diode mount to the TLD001 unit.
4) Connect the TLD001 to the power supply.
5) Attach the power meter to the diode mount.
6) Ensure that the KEYSWITCH on the TLD001 is set to OFF, then turn on the power
to all units.
