Abstract

The invention discloses a passive Q-switched laser with adjustable pulse generation time, which comprises a pumping source (1), the pumping source (1) is connected with a pumping source shaping system (2), and the transmitting end of the pumping source shaping system (2) is provided with a first light beam (3) and a second light beam (4). The first light beam (3) sequentially passes through a first coupling optical system (5), a first laser gain medium (6), a spectroscope (7), a passive Q-switched crystal (8) and a first semi-transparent and semi-reflective mirror (9); the second light beam (4) sequentially passes through the up-down translation type reflecting mirror (10), the first reflecting mirror (11), the second coupling optical system (12), the second laser gain medium (13), the second semi-transparent and semi-reflecting mirror (14) and the second reflecting mirror (15); and the transmitting end of the second reflecting mirror (15) is matched with the incident end of the spectroscope (7). The pulse generator has the characteristic that the pulse generation time can be adjusted.

Description

technical field [0001] The invention relates to a passive Q-switched laser, in particular to a passive Q-switched laser with adjustable pulse generation time. Background technique [0002] Passively Q-switched laser is a pulsed laser that utilizes the nonlinear effect of the crystal to Q-switch the laser. Because the Q-switching mechanism uses the saturation effect of the crystal itself and does not require a complicated external excitation structure, the structure of the passive Q-switched laser is very Simple and compact. However, once the existing passively Q-switched laser is produced, its pulse generation time cannot be adjusted in the use stage, which will limit its application in some fields, resulting in a limited application range. Therefore, the existing technology has the problem that the pulse generation time cannot be adjusted. Contents of the invention [0003] The object of the present invention is to provide a passive Q-switched laser with adjustable puls...
