Abstract

The present invention discloses a pulse laser beam combining device and method based on four electrodes. The device comprises an electro-optical crystal, two drive circuits, at least two lasers, a synchronous machine, and a laser alignment device. The two electrode plates of one drive circuit are matched with the two adjacent side faces of the electro-optical crystal, the two electrode plates of the other drive circuit are matched with the other two side faces of the electro-optical crystal respectively. The output ports of the lasers face the incident surface of the electro-optic crystal. The two drive circuits and all lasers are connected to the synchronous machine. According to the device and the method, the electro-optical crystal with four electrodes is utilized reversely in different voltages such that incident laser light has different deflection paths, the generated light is deflected and is combined with the characteristic of pulse laser and the synchronous machine, and multi-path pulse laser beam combination can be realized through one level of beam combination device.

Description

technical field [0001] The invention relates to the field of high-power lasers, in particular to a four-electrode-based pulsed laser beam combining device and a method thereof. Background technique [0002] With the continuous development and maturity of laser technology, high-power lasers have become more and more widely used, which has profoundly affected the development of many industries. According to the working mode, high-power lasers are mainly divided into high peak power lasers (ie high-energy pulsed lasers) and high average power lasers. [0003] For high-energy pulsed lasers, lasers are required to have a certain repetition rate in various application fields. However, directly increasing the repetition rate of high-energy pulsed laser operation will produce serious thermal effects, which will affect the performance of the laser, and even cause the output pulse energy of the laser to decrease or fail to work. For high-average-power lasers, application requirement...
