Abstract

See full text

The present invention is applicable to the field of fiber laser technologies. In the present invention, two fiber lasers of different bands are used as seed sources to form a dual-band fiber laser that outputs beams of two bands simultaneously, and the dual-band fiber laser is used to pump the cascaded evolving assemblies. Specifically, when the laser beams of the two bands go through a first-stage evolving assembly, the laser of one band is evolved into a visible-to-near-infrared supercontinuum, while the laser of the other band is evolved into an ultra-short pulse; the visible-to-near-infrared supercontinuum and the ultra-short pulse are coupled and enter a second-stage evolving assembly; the ultra-short pulse is further evolved into a near-infrared-to-mid-infrared supercontinuum, in which the visible-to-near-infrared supercontinuum generated at the previous stage is transmitted in a low loss manner; and an ultra-wideband supercontinuum covering visible, near-infrared, and mid-infrared bands is finally output from cascaded fibers.
