Abstract

The invention relates to a laser, in particular to a slab laser with tunable broadband, belonging to the laser technical field. The slab laser with tunable broadband comprises five parts, namely a pumping source, an input mirror, a slab gain medium, a dispersive optical element (such as a dispersing prism, a fiber grating, etc.) and an output mirror. The oscillating light with different wavelengths has different light paths in the laser; all laser nearby a central wavelength can form oscillation and is amplified through the slab gain medium, so as to form wide-line wide-laser output; the central wavelength of the output laser can be changed by regulating the inclination angles of the output mirror, and then the tunable broadband laser output can be realized. The laser of the invention is compact in structure, can change the wavelength of the output laser by regulating the inclination angles of the output mirror, and realizes the tunable broadband laser output.

Description

A broadband tunable slab laser technical field The invention relates to a laser, in particular to a broadband tunable slab laser, belonging to the technical field of lasers. Background technique At present, most of the research work on tunable lasers is focused on single-wavelength, dual-wavelength, and 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 The invention is a laser diode end-pumped broadband tunable slab laser, which aims to use slab gain media such as titanium sapphire and Cr:LiSAF with a wide fluorescent linewidth, combined with a pump source, ...
