Fiber laser double-stroke pumping 1.2-micrometer waveband range laser device

Disclosed is a fiber laser double-stroke pumping 1.2-micrometer waveband range laser device. An Ho3+laser crystal serves as a work material, a 1.13-1.20 micrometer waveband fiber laser device serves as a pumping source, and the Ho3+ doped laser crystal realizes 1.2-micrometer waveband 'p' polarization direction laser output under the excitation of fiber pumping light in the 's' polarization direction. Under the condition that the pumping light wavelength is quite similar to the laser wavelength, a laser resonant cavity and a fiber laser pumping source are effectively separated, the requirement for film coating of a resonant endoscope is lowered, the film coating quality is improved, the energy of the fiber pumping light is fully used, and the fiber laser double-stroke pumping 1.2-micrometer waveband range laser device is a novel 1.2-micrometer waveband range solid laser device which is high in light beam quality, compact in structure, safe in work and wide in application prospect and has quite important application value in the fields of medical service, aviation and the like.
