3.1.2. Cooling
The laser performance is highly dependent on its operating temperature, it is therefore
necessary to cool down the laser accordingly. The following setups can be used:
• for LLH only: closed loop cooling system with chiller
• for LLH only: tap water, Swagelok fitting to the tap, 4 mm tubing
• good mechanical contact between the LLH or HHL housing or QCL submount
and the heat sink, such as an optical table
• heat sink and fan
CAUTION:
Overheating the laser chip may result in permanent damage.
