Temperature regulating laser diode assembly

(57) A summary advanced type laser diode assembly contains the laser diode unit (52) carried on the heat sink (58). The insulative gasket (64) carried in the circumference of the small thermostat electric air conditioner (54) prevents the condensation (cloudy weather) produced from ambient environment on the cold surface (102) of an air conditioner by sealing this air conditioner. Bushing (66) changes intensive arrangement into a corresponding optical assembly and the right optical alignment state, when allotting this laser diode unit thermally and electrically. A heat conduction gasket (92) is carried in the circumference of a window of this laser diode, and prevents the cloudy weather which returns heat from a heat sink to this window, and is produced in the window. A laser diode is the only element cooled by this air conditioner. The component for heating separated since a part of heat carried by the air conditioner was used in order to warm the window of a diode is unnecessary, and this increases the efficiency as this whole laser diode.
