Supply device for a gas mixture laser apparatus and laser apparatus provided with such a device |
摘要 |
The laser (1) is supplied with e.g. nitrogen and carbon dioxide gasses through separate ducts (25,29), one (25) of which passes through an expansion turbine (27). The discharge is excited e.g. in whispering-gallery mode in the resultant mixt., which is water-cooled (33) and recycled through a compressor (35) driven by the turbine. After compression the recycled mixt. undergoes further cooling (37) and compression (39) before entering a separator (45). The CO2 permeates into the duct leading directly back to the laser, while the remainder comprising almost pure N2 is returned via the expander. |
