Abstract
A laser apparatus has a laser device, a first reflection mirror, an output mirror and a second reflection mirror. The laser device oscillates first and second laser light beams. The first reflection mirror reflects a first laser light beam and is fixed at one end of an optical axis. The second reflection mirror reflects a second laser light beam and is arranged between the laser device and the first reflection mirror so as to be movable with respect to the optical axis. The output mirror reflects the first and second laser light beams and is fixed at the other end of the optical axis. With such a structure, the second reflection mirror is set to first and second positions. Specifically, the second reflection mirror is remote from the optical axis in the first position. Consequently, the first laser light beam is amplified between the first reflection mirror and the output mirror. On the other hand, the second reflection mirror is placed on the optical axis in the second position. Consequently, the second laser light beam is amplified between the second reflection mirror and the output mirror.
