Abstract: A gaseous laser includes a gas discharge tube (12) made of a comparatively thin-walled ceramic tube (26). Heat from the discharge is transmitted to the exterior tube by conduction through thin-walled, cup-shaped members (50) which are assembled and aligned in a spaced-apart relationship within the tube (26). Bore-defining apertures (46) in the heat-conducting members (50), or in sputter-resistant discs (48) affixed to the heat-conducting members (50), are aligned by a mandrel (74) under tension at which time the parts are permanently bonded within the tube (26). Also coaxially affixed to the cup-members (50) are cylindrical shields (56) which control gas pumping within the tube (26). Gas return holes (54) are provided in the cup-members (50).

Abstract: A pulsed solid state laser system (10) is disclosed which utilizes a plurality of individual laser rods (11-14) which are sequentially pumped and whose beams are combined into a single interleaved ouput beam (34). The individual laser rods (11-14) are pumped at an average power level which is below that for maximum output power from each rod, thereby obviating the need for refrigeration cooling. A compact optical system is disclosed which permits a constant beam size even at different pump levels and other advantages. A compact cooling system is also disclosed.
