This technical note describes the thermal resistance of the LRS-9550-4442B C-Mount Fixture. Thermal resistance was characterized across all device locations and with different device loading patterns.The LRS-9550-4442B fixture is designed for high power C-mount devices with drive currents up to 20A and is compatible with the LRS-9550 High Power Laser Diode Test System. Depending on the application and system configuration, the Cmount fixture can be loaded with either 8 or 16 Cmount laser diodes. Devices are arranged in two rows on either side of the fixture and are electrically connected in series. Figure 1 illustrates arrangement and numbering of devices.
