Description

technical field

[0001] The invention relates to the field of lasers, in particular to a visible light enhanced supercontinuum laser system with an all-fiber structure. Background technique

[0002] When laser pulses are transmitted in highly nonlinear media, various nonlinear effects will occur, which broaden the spectrum to hundreds of nanometers or even wider. This extreme spectrum broadening phenomenon is called the generation of supercontinuum. Compared with other light sources, the supercontinuum light source has many advantages such as continuum bandwidth, stability and reliability, and good coherence. Supercontinuum laser has very important application value in many aspects such as biomedicine, optical metrology, optical communication, coherence measurement, optical display and spectral analysis. The supercontinuum in the visible light band is of inestimable value in the fields of laser display, biological spectrum analysis, and photoelectric countermeasures. Compar...
