| Zusammenfassung: | The invention provides an intermediate infrared laser generation device. The intermediate infrared laser generation device comprises a cover plate, an optical layer, a refrigeration layer and a heat dissipation layer, the optical layer comprises an input optical fiber, a collimation coupling mirror group, an annular resonant cavity, an output coupling mirror group and an output optical fiber; wherein the collimating coupling mirror group comprises a first collimating lens and a second collimating lens.The output coupling mirror group comprises a first output coupling mirror, a spectroscope anda second output coupling mirror; rhe annular resonant cavity comprises a front cavity mirror, a periodically poled crystal, a rear cavity mirror, a first plane mirror, an interferometer and a secondplane mirror. The front cavity mirror, the rear cavity mirror, the first plane mirror and the second plane mirror form a parametric resonant cavity of an annular structure. The collimating coupling mirror group is arranged bet |
