The LDM-4415 Laser Diode Mounting Fixture provides a compact, easy to use solution for mounting and temperature controlling CS packaged conductively cooled high power laser diodes. Heat sink technology developed at ILX Lightwave allows the 4415 to dissipate up to 100 W of heat generated by the laser diode with an active temperature control range of +20C to 85C. Fixture design and precision machining result in repeatable thermal resistance between the CS packaged device and mounting block, minimizing the temperature difference between the laser and the fixture. The LDM4415 is compatible with ILX Lightwave high power current sources and temperature controllers through interconnect cabling allowing up to 120A of laser diode current for the highest power conductively cooled laser diode bars. Optical table mounting is made possible through standard 1" spaced mounting holes on the base of the mount.
