Abstract

The invention discloses a laser device Q switch performance test method and a laser device Q switch performance test device. The device includes a continuous laser device, a polarizer, a 1 / 4 wave plate, a polarization analyzer and a laser energy meter which are sequentially and coaxially arranged according to the light path direction, a Q switch to be tested is placed between the 1 / 4 wave plate and the polarizer; the device also includes a rotary rack with scale marks; the polarizer, the Q switch, the 1 / 4 wave plate and the polarization analyzer are installed on the rotary rack with the scale marks for metering phase orientation of the rotary rack. According to the laser device Q switch performance test method and device, a quantitative method is provided for testing and adjusting Q switch performance through measuring energy changes of the continuous laser after passing through the light path, and can be well applied to testing and maintaining pulse laser device Q switch performance.

Description

technical field [0001] The invention relates to the field of performance testing of laser components, and more particularly, to a method and device for testing the performance of a Q-switch of a laser. Background technique [0002] The Q switch is a key component in a pulsed laser, and its switching performance directly affects the light extraction efficiency and energy of the laser. The Q switch is composed of Q-switching components, polarizers & 1 / 4 wave plate components, and the relationship between the optical components in each component directly determines its switching performance. It is necessary to test the performance of the Q switch and adjust its state to the best state to ensure the maximum pulse energy output during the initial installation and adjustment of the laser or maintenance inspection and adjustment. The existing test method is: place the Q switch in the optical path of the pulse laser, and determine whether the performance of the Q switch is normal b...
