How to get started
Step
What to do
Check
1
Unpack your device.
2
Attach the laser diode to the driver.
Please see section “Connection of
the Laser Diode” for further
details.
3
Assemble the driver onto an appropriate
heat sink. This step may only be omitted if
the stress to the driver is kept very low.
See section “Power Losses” for
further information on thermal
dissipation.
4
Connect GND, +5 V and +HV to the
10 pin Micro-Match connector. Keep the
power supply off.
Please see section “How to
connect the Driver” for further
details.
5
Connect the pulse generator to the SMA
trigger input jack.
Ensure that no pulse is fed before
powering up the unit.
6
Carry out the power-up sequence as
follows:
1) Fully ramp up the +5 V rail
2) Enable the +HV supply
Then, feed a pulse signal to the input
terminal. For example 5 V amplitude,
100 µs pulse width and 1 kHz repetition
rate.
Security advice: Do not touch the
PCB components near the laser
diode since they may carry high
voltages up to 100 V.
Note: Observe the drivers limits as
in section “Power Losses” to avoid
overloading the driver.
7
Check the optical output of your laser
diode.
8
Turn off sequence:
Disable the pulse generator and then turn
off all power sources (+5 V and +HV).
