Abstract

A laser light source relates to the technical field of laser and includes a control system module, a processor module, a pulse shape amplification module, a constant current source module, a couplingmodule, a temperature control module and a laser diode. As the control system module generate a parameter adjust signal according to preset laser parameters, the processor module may generate an electrical pulse of a specified parameter according to the parameter adjustment signal, Finally, the laser diode generates optical pulses with specified parameters according to the electric pulses, The pulse shaping amplification module can filter the noise in the electric pulse and amplify the electric pulse, so that the laser light source can output stable power. The temperature control module can collect the working temperature of the laser diode in real time and control the working temperature of the laser diode to keep at the preset working temperature. The laser source has the advantages of real-time adjustment of optical pulse parameters, stable output power and low operating temperature offset.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a laser light source. Background technique [0002] With the development of science and technology, lasers have been widely used in various fields of industrial and agricultural production and science and technology, so the development and research of laser light sources have also received further attention from scientific researchers. [0003] In the prior art, laser light sources mainly include: Q-switched-mode-locked fiber lasers, traditional semiconductor laser light sources, and fast thyristor-avalanche transistor switching circuits. Q-switched-mode-locked fiber laser is an effective means to realize high-energy laser pulses. The Q value of the laser is adjusted by modulating the cavity loss in the laser cavity. The traditional semiconductor laser light source realizes the particle number inversion of non-equilibrium carriers between the energy bands of the semiconductor mat...
