Abstract

The invention discloses a super-continuum spectrum laser light source, belongs to the technical field of laser devices, and solves the problem of low laser output conversion efficiency of an existingultra-wideband super-continuum spectrum laser light source. The super-continuum spectrum laser light source comprises: a laser pumping source; a lens group which is arranged on the emergent light pathof the laser pumping source and is used for collimating and focusing the emergent light of the laser pumping source; and a thin-film waveguide device which is arranged on an emergent light path of the lens group, wherein light entering the thin-film waveguide device can be emitted out after a nonlinear effect occurs in the thin-film waveguide device, the thin-film waveguide device comprises a polarized crystal, and the polarized crystal is of a chirped domain structure. The super-continuum spectrum laser light source is used for generating the super-continuum spectrum laser.

Description

technical field [0001] The invention relates to a supercontinuum laser light source, belonging to the technical field of laser devices. Background technique [0002] With the continuous development of science and technology, the supercontinuum, which has the advantages of wide spectral width, good spatial coherence, and high brightness, is playing an increasingly important role in the fields of biomedical research, environmental monitoring, optical precision measurement, material processing, and national defense security. role. At present, there are supercontinuum light sources in the ultraviolet, visible, near-infrared, and mid-infrared bands, as well as ultra-broadband supercontinuum light sources that can simultaneously cover the visible, near-infrared, and mid-infrared bands. towards commoditization. [0003] In practical applications, due to the wider spectral width of the ultra-broadband supercontinuum light source that can simultaneously cover the visible, near-infr...
