The source of high power fiber pump light provided with the high-intensity low noise output in the wavelength range of about 974-1030 nm

Japanese Patent JP6058669

B2

A high power pump ultra bright low-noise source is configured with a multimode (“MM”) seed source outputting a MM smooth, low-noise signal light at a desired wavelength in a wavelength range between about 974 and 1030 nm, a MM Yb fiber wavelength converter operative to convert emission of a plurality of high power (“HP”) semiconductor laser diodes at a sub-pump wavelength λsp to a pump output at the desired wavelength λρ, wherein Δλ=λρ−λsp<0/1λsp. The Yb-doped MM wavelength converter is configured with noise levels substantially identical to those of the low-noise signal light, brightness (“B”) substantially equal to Π×B, wherein n is a number HP semiconductor laser diodes, and B is brightness of each HP laser diode, and output power (“Po”) substantially equal to nPd, wherein Pd is a power of each HP laser diode, and n is the number thereof.
