NOVELTY - The utility model claims a composite material based on MoS2/NG of all-solid-state infrared pulse laser, comprising sequentially connected semiconductor laser, a coupling lens group, Tm: YLF crystal, plane mirror, the first plane concave lens. the second plano-concave mirror, reflector, the MoS2/NG composite material can be saturated absorber, outputting mirror, through fibre output semiconductor laser generating 792 nm continuous light of the Tm: YLF crystal, output by the continuous light mirror 1910 nm. in the infrared pulse laser is reflected twice by the first plano-concave mirror, the second plano-concave mirror, then by the reflector emission enters the saturable absorber MoS2/NG composite material, then outputting 1910 nm waveband by the output mirror. The utility model claims a medium infrared pulse laser, using the MoS2/NG composite material of the saturable absorbing characteristic, and it can get high energy in the infrared pulse laser to realize the nanosecond pulse output.
