Abstract

The invention discloses a novel mode-locked laser, and relates to the technical field of lasers. The device comprises a laser chip; one side of the laser chip is provided with a VBG grating, one side of the VBG grating is provided with a fast axis collimating lens, and one side of the fast axis collimating lens is provided with a slow axis collimating lens; the laser chip comprises an active layer, the rear end face of the laser chip is plated with a high-reflectivity thin film, the front end face of the laser chip is plated with an antireflection film, and the high-reflectivity thin film corresponds to the VBG grating. The volume grating is arranged on one side of the laser chip, the laser chip emits light, and the light is partially reflected back to the laser chip by the volume grating, so that the emission wavelength of the laser chip is single and stable, and the laser which is output and coupled by the volume grating has the advantages of small output line width and high temperature stability; the structure is compact, medium in the laser cavity is less, and the property is more stable.

Description

technical field [0001] The invention belongs to the technical field of lasers, and in particular relates to a novel mode-locking laser. Background technique [0002] As a key core component, high-power semiconductor laser chips are mainly used in industrial processing, medical beauty, optical communication, security protection, intelligent perception, scientific research and other fields. According to application requirements, its wavelength ranges from 405nm to 1620nm; its single-tube chip power ranges from 0.5W to 30W; its bar chip power can reach 200W. Using the optical feedback of Bragg volume gratings, the wavelength locking and spectral linewidth narrowing of high-power laser chips can be achieved to enhance its pumping efficiency, increase the technical route of subsequent laser beam combining, and expand its application range. [0003] The existing laser mode locking technology uses Bragg volume grating as the output coupling mirror of the laser. The Bragg volume g...
