Problems solved by technology

[0004] In summary, the existing problems in the prior art are: since ceramics are polycrystalline, the internal grain boundaries, pores, and imperfections in the crystal lattice will lead to the opacity of the material and increase the scattering loss of light. There are some difficulties in using laser media

Abstract

The invention belongs to the technical field of laser, and discloses an all-solid-state Tm:LuScO3 Q-switched mode-locked ceramic laser. The laser comprises the components of a pumping source which isused for generating pumping laser with wavelength of 795.7nm; a focusing lens which is used for realizing high transmission rate to the pumping laser and focuses the pumping laser into crystal; a Tm:LuScO3 ceramic laser gain medium which is used for changing the pumping laser with central wavelength of 795.7nm to the laser in a 2[mu]m wave band; a laser resonator which is used for realizing operation of the laser in the 2[mu]m wave band; and an oxide graphene saturable absorber which is used for converting output continuous light to pulse light. The invention provides a solid laser source which emits the laser in the 2[mu]m wave band and in a water molecule strong absorption wave band, such as laser distance measuring machine, coherent Doppler wind measurement radar, water vapor parabolicsurface differential absorption laser radar system, laser ophthalmologic operation and laser micromachining.

Description

technical field [0001] The invention belongs to the technical field of lasers, in particular to an all-solid-state Tm:LuScO 3 Q-switched mode-locked ceramic laser. Background technique [0002] All-solid-state ultrashort pulse lasers have the advantages of high efficiency, stable performance, long life, and high beam quality, so they have always been one of the research hotspots of ultrafast laser technology. Eye-safe 2μm band all-solid-state Tm:LuScO 3 Ceramic lasers, whose central wavelength is located in the strong absorption band of water molecules at 1800-2000nm, have great application potential. It can be used as an ideal light source for laser rangefinders, coherent Doppler wind radars, water vapor throwing surface differential absorption lidar systems, laser eye surgery, and laser micromachining. Laser transparent ceramics are another noteworthy laser gain medium after single crystal and glass, which has the advantages of both crystal and glass materials, and prov...
