Abstract: An all-fiber color laser and a light-illuminating method thereof are disclosed. The steps of the light-illuminating method include: providing a fiber color laser having a pump light source and an optical fiber with a multi-level wavelength gain medium, a first grating assembly and a second grating assembly; radiating a laser via the pump light source; generating a plurality of laser beams with various wavelengths via the multi-level wavelength gain medium; adjusting the deformation of the second grating assembly to control output of the laser beams with various wavelengths; and executing periodical modulation to generate a periodical lengthwise deformation of the second grating assembly for mixing color.

Abstract: A fiber side-coupling apparatus can be spliced with active fiber as a fiber-based side-coupler in series at both sides for distributively-pumped monolithic fiber lasers. This side-coupling apparatus includes a large-mode-area double-clad passive optical fiber. A cladding grating, formed on the cladding surface of the passive fiber, comprises a plurality of grating members and a reflection layer formed thereon. A laser diode bar array is disposed on one side of the optical fiber opposite the cladding grating. A collimation device, placed between the optical fiber and the laser diode bar array, is used to collect the pump beam to the cladding grating as much as possible in fast axis and collimate the pump beam to be incident to the cladding grating in slow axis as normally as possible. The collimated pump beams emitted from a laser diode bar array are normally incident to the cladding grating within the alignment tolerance of ±2 to ±4 degrees. Without the reentrance loss effect, the pump beams diffracted and reflected by the cladding grating propagates in the inner cladding of the passive fiber due to total internal reflection. In one embodiment, the grating member can be a binary or blazed cross section.
