Thermal management
To ensure operation within given specifications and for the warranty to be valid, the laser head must be mounted on
a suitable heat sink. The requirement on thermal resistance of the heat sink can be calculated by taking the difference
between the maximum allowed laser head base plate temperature (50 ºC) and the ambient temperature at the air-
heat sink interface (e.g. 40 ºC), divided by the maximum power dissipated from the laser; 12 W for 06-MLD and 20 W
for 06-DPL. The 06-MLD laser head must be attached to a heat sink providing a thermal resistance of < 0.8 K/W at
40°C ambient temperature and the 06-DPL requires a heat sink with a thermal resistance of < 0.5 K/W. The mounting
surface should be flat within 0.05 mm over mounting surface. Under normal circumstances thermal heat compound
is not required, however if the laser is operated in an area with a high ambient temperature it is recommended to use
a thermally conductive compound between the laser head and the heat sink to provide good thermal contact. For
assistance in thermal management and system integration, please contact Cobolt’s technical support.

Power supply requirements
An appropriate Power Supply Unit (PSU) is supplied by Cobolt with the laser and can be plugged into a standard power
outlet. The power supply accepts 90-264 VAC and 47-63 Hz. Ripple and noise 1% peak-peak max, 20 MHz bandwidth.
Accepted voltage range for the laser head is (5.0 ± 0.4) VDC. Specification values are given at 5 VDC.
