5.3. General procedures

CAUTION:

The laser shall only be operated under conditions as speciﬁed in

the datasheet or by ALPES LASERS directly: all other operation may

result in the destruction of the laser and loss of warranty.

5.3.1. QCL startup

In order to insure the laser’s performance and enhance its lifetime, the following steps

must be followed thoroughly:

1. make sure all devices are turned off

2. start cooling for LLH or HHL housing (see section 3.1 for prerequisites)

CAUTION:

The laser must be used at the temperature speciﬁed in the datasheet.

Operating the laser below or above the given temperature is likely to

damage the laser and will result in the loss of warranty.

Contact ALPES LASERS or a representant before using the laser at a tempera-

ture outside the range speciﬁed in the datasheet.

3. startup the TCU following procedure 5.1.1

4. if the laser is operated in CW mode, follow procedures included in the CW laser

driver OEM manual. Always keep the current 1mA above 0 to avoid reversing

the polarity.

5. if the laser is operated in pulsed mode:

a) startup the external power supply:

i. connect the external power supply to mains

ii. remove the red/black banana cables

iii. turn on the external power supply

iv. set the voltage and current to 0, but keep the voltage 100 mV above 0

to avoid accidental polarity reversal

v. turn off the external power supply
