Abstract

The invention relates to the technical field of intermediate infrared ultrashort pulse laser, in particular to an all-solid-state broadband tunable intermediate infrared ultrashort pulse laser. The laser comprises a laser pumping source, a first dichroic mirror for splitting laser generated by the laser pumping source, a first laser resonance part positioned on a reflection light path of the firstdichroic mirror, a second laser resonance part positioned on a transmission light path of the first dichroic mirror, a first convex lens positioned at the input end of the first laser resonance part,a third convex lens located at the input end of the second laser resonance part, a third dichroic mirror located at the intersection of a reflection light path of a first feedback terminal of the first laser resonance part and a reflection light path of a second feedback terminal of the second laser resonance part, and a wavelength tuning module located at the beam combination output end of the third dichroic mirror. And a ninth dichroic mirror is arranged at the intersection of the output light path of the first laser resonance part and the output light path of the second laser resonance part, so that tuned intermediate infrared ultrashort pulse laser is output.

Description

technical field [0001] The invention relates to the technical field of mid-infrared ultrashort pulse laser, in particular to an all-solid-state broadband tunable mid-infrared ultrashort pulse laser Background technique [0002] The 3-5 μm mid-infrared ultrashort pulse laser has been widely used in recent years due to its great application prospects in many fields such as time-resolved spectroscopy, semiconductor dynamics research, special material fine processing, minimally invasive biological tissue, and supercontinuum laser generation. Attention, at present, the methods for realizing mid-infrared laser output mainly include methods such as semiconductor lasers, gas lasers, solid-state lasers, and free electron lasers. Among them, solid-state lasers have become the best choice for realizing mid-infrared laser output due to their advantages such as high efficiency, small size and light weight. The most effective and practical technical approach. Specifically, mid-infrared s...
