Device for laser beam amplification

摘要

The device (21) has a booster chamber (22) with laser-active material such as carbon dioxide. A transmissive optical element (23) i.e. diamond window, defines the booster chamber, and is arranged perpendicular to an optical axis (26) of a laser beam (10) at tilt angle in an oriented plane. A detection unit (24) is arranged at outer side of the booster chamber, and detects transmission of back-reflected laser beam (27) on the optical element. A deflecting mirror turns the back-reflected laser beam on the detection unit.
