Abstract

The invention relates to an electro-optic Q-switched solid laser. The electro-optic Q-switched solid laser comprises a laser resonant cavity formed by an output mirror, a laser medium and a total reflective mirror, wherein a polaroid and an electro-optic Q-switched crystal are arranged between the laser medium and the total reflective mirror sequentially, and the electro-optic Q-switched crystal is connected with an electro-optic Q-switched driver; the electro-optic Q-switched driver comprises a high-voltage source, a trigger circuit and a switch; the switch comprises a first end for being connected with one end of the electro-optic Q-switched crystal, a second end for being connected with the other end of the electro-optic Q-switched crystal and the ground and a third end for controllingon and off of the first end and the second end. According to the electro-optic Q-switched solid laser, two kinds of driving, namely, decompression or pressurization, can be realized, the output pulsewidth of laser pulses is accurate and controllable, and the output pulse width of the laser can be reduced.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to an electro-optic Q-switched solid-state laser. Background technique [0002] The electro-optic Q-switching method is a technology that uses the electro-optic effect of crystals to adjust the Q value, so that the laser can output laser with high peak power and narrow pulse width. However, the pulse width of the general electro-optic Q-switched laser output is about 30ns. In laser detection and laser display, the lower the pulse width of the laser pulse, the higher the display accuracy. Laser pulses below 20ns will improve the accuracy of laser detection and laser display, which cannot be achieved by current electro-optic Q-switched lasers. In addition, the current electro-optic Q-switching driver can only work in one working mode. If a different mode is to be used, the electro-optic Q-switching driver needs to be replaced, which increases the cost. Contents of the invention ...
