Abstract
A conductively cooled flashlamp (30) for use solid state lasers. The flashlamp (30) has an elongated heat sink (31) with a reflective center channel (32), and a flashlamp tube (12) disposed in the channel (32) that extends beyond the ends of the channel (32). Heat conducting gaskets (37a, 37b) are disposed around respective ends of the envelope (34) that separate the tube (12) from the heat sink (31) to provide an air gap (35) therebetween. Clamps (36a, 36b) contact the gaskets (37a, 37b) and secure the envelope (34) to the heat sink (31). Electrodes (25a, 25b) of the tube (12) extend away from the ends of the tube (12) and heavy wires (38a, 38b) are connected to the electrodes (25a, 25b) and extend longitudinally away from the respective electrodes (25a, 25b). Heat conducting, electrically insulating heat sink members (41a, 41b) are disposed at opposite distal ends of the heat sink (31), and wire clamps (42a, 42b) secure the wires 38a, 38b to the heat sink members (41a, 41b). Thus, the tube (12) is disposed in close proximity to the reflective heat sink (31), which does not directly contact the tube (12). The tube (12) is clamped with good thermal contact to the heat sink near the…
