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 20 to 85 °C. 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.
For characterization over temperature of your CS packaged devices, the LDM-4415 comes with integrated thermoelectric modules and water cooled heat sink for a control range of +20C to 85C. Lower control temperatures can be reached with heat loads <100W. The high power TECs have the thermal performance to dissipate up to 100W head load from conductively cooled CS packaged devices. A hybrid D-sub temperature control connector is provided for compatibility with ILX Lightwave LDT-5900 Series Temperature Controllers.
Careful attention to the mechanical design results in a low thermal resistance between the CS package and the mounting block. Torquing the device to the recommended value provides constant and repeatable clamping pressure on the CS package ensuring best thermal performance and helps eliminate measurement inconsistencies.
The LDM-4415 is compatible with ILXs LDX-3600 Series High Power Drivers through interconnect cabling. Connections for laser drive current, forward voltage measurement, and temperature control are provided on the rear panel of the ﬁ xture. Auxilary anode and cathode connections are provided on the rear panel with #10-32 lugs for connection to other power supplies.
Optical table mounting is made possible through standard 1 spaced mounting holes on the base of the mount. Additionally, the LDM-4415 is designed for integration into optical test systems with unobstructed laser facet access at the front of the ﬁxture.
