The LDM-250W high power laser diode heat sink and mount is a high-performance cooling solution designed for fiber coupled and free-space laser diode packages. It is an “all-air” cooling design. The heat from the laser diode is pumped through the laser mounting plate and is removed from the assembly through the fan located in the base.
Fan Cooled Heat Sink
The heat emitted from the laser diode is conducted down through the laser mounting plate through a low thermal impedance plate surface. Two high CFM fans located in the base dissipate the heat from the base of the block into the air. The LDM-250W offers a low thermal impedance of < 0.059 K/W mounting surface for the laser being tested. Thermal performance of a heat sink is highly dependent on the thermal impedance, or resistance. This measurement is defined in units of degrees Celsius per watt of heat°C/W. The thermal resistance allows the user to determine the amount of temperature rise that the laser diode will experience for each watt of thermal energy that is emitted by the device under test. The dual fans in the base greatly improve the thermal performance of the heat sink and allow the user to set the laser temperature to a set-point which is equivalent to the lab ambient temperature. Careful machining of the mounting plate surface finish and surface flatness are also crucial to the heat sink performance.
