Abstract

The embodiment of the invention provides a current adjustment method of a laser and related device and equipment thereof. The current adjustment method of the laser comprises the steps of acquiring target output energy of the laser; acquiring a working temperature of the laser; inquiring a relation between preset output energy corresponding to the working temperature and a current; and determining the current corresponding to target output energy according to the relation between the output energy and the current, and adjusting the current of the laser to the determined current. With the current adjustment method provided by the embodiment of the invention, the laser can reach the target output energy expected by a user, and the output energy of the laser is maintained stable.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a laser current adjustment method and related devices and equipment. Background technique [0002] In the prior art, a laser amplifier side-pumped by a laser diode array includes a working medium and a pump source surrounding the working medium. The working medium usually adopts yttrium aluminum garnet (Nd:YAG, Neodymium-doped YttriumAluminium Garnet; Nd:Y3Al5O12) crystal rod, the pump source is composed of multiple monochromatic laser bars, and the crystal rod is used to absorb the pump source The emitted light and realize photon transition. [0003] The defect existing in the prior art is: as the environment changes, the output energy of the laser amplifier will also change and cannot be kept stable. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a laser current adjustment method and related devices and equipment...
