3.3 Connections

3.3.9. Connection procedure

The procedure to connect the Starter Kit components depends on the laser housing

and operation mode. Refer to ﬁgure 3.4 for cable identiﬁcation.

In all cases

To prevent any damage to the Starter Kit components, make sure the TPG, TCU and

the external power supply are all turned off.

CAUTION:

Make sure that the connectors polarity is correct: the laser’s ground

must be ﬂoating for both its anode and cathode. Inverting the

connector’s polarity may result in permanent damage to the laser.

CW mode operation

• LLH housing in CW mode:

1. connect the LLH to the TCU using the CTL cable

2. connect the ILX to the LLH using the CIL cable

3. if available, connect the cooling water tubing to the corresponding connec-

tors of the LLH

Note: if no water cooling is being used, carefully monitor the LLH module

case temperature. Air cooling and heat dissipation must be provided.

CAUTION:

If the LLH module case exceeds a temperature of 60

◦

C, permanent

damage to the laser chip may occur.

• HHL housing in CW mode:

1. connect the HHL to the TCU using the CTLm

2. connect the ILX to the HHL using the CIL cable through the CTLm cable
