| 摘要 |
The present invention relates to a laser apparatus (100), comprising: a pulse generator (10) installed to irradiate, amplify, and resonate a laser beam between a high reflector mirror (60) and an output coupler mirror (30); a pulse output unit (70) for receiving the laser pulse amplified and resonated by the output coupler mirror (30) and for outputting same; and a Q-switch (20) installed to oscillate perpendicularly to and from a path of a laser beam formed between the pulse generator (10) and the high reflector mirror (60). The output coupler mirror (30) includes a first mirror (31) and a second mirror (32) arranged on a base plate (33), and the first mirror and second mirror are configured to selectively move positions according to whether or not the Q-switch (20) oscillates so as to lie within the laser beam path. |
