Bandleiterlaser mit einem optischen Abbildungssystem zur Strahlformung

摘要

The invention relates to a slab laser, especially a CO2 slab laser, comprising an optical imaging system for shaping a laser beam (LS) leaving a resonator (4). The divergence of said beam is smaller in a first direction (14) which is perpendicular to the direction of propagation than in a second direction (16) which is perpendicular to the first direction and to the direction of perpendicular. According to the invention the optical imaging system comprises a first optical imaging element (24) for focusing the laser beam (LS) in the first direction (14) and collimating the laser beam (LS) in the second direction (16), as well as a second optical imaging element (26) for collimating the focused laser beam (LS) in the first direction (14).
