Air cooled gas laser

摘要: A gas laser design (10) includes, an elongated sealed tube (21) filled with a gas, power supply for exciting the optical resonator (24,25) producing directional energy, and fan/electronics package assembly (50), all of which are surrounded enclosed by external housing (30,70,90) forming passageway in space between providing cooling air therethrough. The is divided into two physically separated paths horizontal surface (21a or 41). lower dual L-shaped path defining first downwardly at inlet end vertical channels (31,32) formed contoured shape rearwardly (33) through spaces (27,29) fins (26,28) to outlet (101) rear tube. upper defines second from horizontally (64) around over electronics (50) mounted that portion U-shaped finned heatsink channel (53), (61,63) (62,64) atmosphere end. zone (44) under fan (52) common both paths. All components related within outer compact, high power, thermally stable, assembly.
