Embodiment Construction
[0020] The present invention will be described in detail below with reference to the examples, but the present invention is not limited to these examples.
[0021] Embodiments of the present invention provide a supercontinuum laser light source, such as figure 1 As shown, it includes: a laser pump source 1; a lens group 2, the lens group 2 is arranged on the exit light path of the laser pump source 1, and is used for collimating and focusing the exit light of the laser pump source 1; a thin film waveguide device 3 , the thin film waveguide device 3 is arranged on the outgoing light path of the lens group 2, and the light incident into the thin film waveguide device 3 can be emitted after a nonlinear effect occurs in the thin film waveguide device 3; the thin film waveguide device 3 includes a polarized crystal 31, and the polarized Crystal 31 is a chirped domain structure.
[0022] Among them, the laser pump source 1 is commonly used as a near-infrared supercontinuum laser pu...
