Thermal Management
To ensure operation within given specifications and for the warranty to be valid, the laser head must be attached to a
heat sink providing adequate thermal resistance. The required thermal resistance for low power models is <0.6 K/W
and <0.4 K/W for high power models (i.e Calypso 100 mW, Samba 300 mW, Samba 400mW, Jive 200mW, Mambo
100mW, Flamenco 100 mW, and Rumba 400 mW). This value is the difference between the maximum allowed laser
head base plate temperature (50
º
C) and the maximum specified ambient temperature at the air-heatsink interface
(40
º
C), divided by the maximum power dissipated from the (15W or 25W depending on laser model, see specification
below). The mounting surface should be flat within
0.05 mm over mounting surface. It is recommended to use a
thermal heat compound between the laser head and the heat sink to provide good thermal contact.
The Cobolt ‘HS
-
03 Laser Head Heatsink
’ meets these requirements, see
for more information on heat sinks. For
assistance in thermal management and system integration, please contact Cobolt technical support.
Heat Sink Requirements and typical maximum heat dissipation for Cobolt 04-01 Series. *High power applies to the following models
only: Calypso 100 mW, Samba 300 mW, Samba 400 mW, Jive 200 mW, Mambo 100mW, Flamenco 100 mW, and Rumba 400 mW
Power Supply Requirements
An appropriate Power Supply Unit (PSU) is supplied by Cobolt with the laser and must be plugged into a properly
grounded standard power outlet. The output from this PSU is 12 VDC/5 A. The power supply accepts 100
–
240 V AC
and 50-60 Hz. Ripple and noise 1% peak-peak max, 20 MHz bandwidth. The accepted voltage range is 11 V - 28 VDC.
