Embodiment 1

[0012] like figure 2 As shown, a broadband tunable slab laser of the present invention is composed of five parts: a laser light source 1 , an input spherical mirror 2 , a titanium sapphire slab gain medium 3 , a dispersion prism 6 , and an output mirror 5 . The output wavelength of the laser light source is 532nm, which generates signal light and idler light with wavelengths of 647nm and 3μm respectively, and the size of the gain medium is 10×10×2mm 3 . By adjusting the inclination angle of the output mirror, the output center wavelength can be continuously tuned, thereby realizing broadband tunable laser output.

Abstract

The invention relates to an oscillator, in particular to a laser parameter oscillator that is tunable in broad band, which belongs to the laser technical field. The tunable laser parameter oscillator of the invention comprises a laser light source, an input spherical mirror, lath nonlinear optical material, dispersion optical elements (like a dispersion prism, a fiber grating, and the like) and an output mirror. The laser parameter oscillator of the invention has the advantages of wide output linewidth, tunable center wavelength and simple structure.

Description

technical field [0001] The invention relates to an oscillator, in particular to a broadband tunable laser parametric oscillator, belonging to the technical field of lasers. Background technique [0002] At present, most of the research work on tunable lasers is concentrated on single-wavelength, dual-wavelength, narrow-linewidth operation, but there are few reports on wide-linewidth output tunable lasers. Wide linewidth tunable lasers have important applications in optical communication, environmental monitoring, laser remote sensing, lidar and other fields, especially in electro-optical countermeasures. At present, there is no relevant report in the literature at home and abroad to obtain wide linewidth laser output by using the Fangming scheme. Contents of the invention [0003] The invention aims to use nonlinear optical materials such as LBO, BBO, KTP, etc., and combine laser light sources, resonant cavity mirrors, and dispersion optical elements to form a broadband t...
