This technical note presents the results of thermal power (heat) dissipation measurements on a typical LDM-4616 16-Channel Laser Diode Mount and explains how ILX Lightwave calculated the thermal resistance of the mount.When operating laser diode modules, heat is generated within the laser diode. A thermoelectric cooler (TEC) is commonly used to cool the laser diode by transferring heat from the laser diode to the module case. In addition, the TEC itself produces joule heating from the power applied to it. Heat must be dissipated into the environment to keep the module case temperature within operating range. A good laser diode mount will absorb heat from the module case and dissipate heat into the environment efficiently.
