Thermal Resistance of the LDM-4409

Contact thermal resistance is a result of surface imperfections between two mating surfaces and characterized by a temperature difference between the two surfaces under a given heat load. It is quantified in °C/W and is related to the surface finish, clamping force and materials used for the mating surfaces. Thermal resistance between a laser diode and a mating surface becomes an issue with high power laser diodes for the simple reason that the higher heat loads lead directly to an increase in temperature of the laser.
