摘要

High-power high-brightness pump source is a low noise , a smooth low noise signal light of multi-mode (MM) in the wavelength range of 974~1030nm and multimode (MM) seed source for outputting at the desired wavelength , the plurality of sub-pump at a wavelength sp configuration de luminescence of high power (HP) semiconductor laser diodes , multi-mode (MM) Yb fiber wavelength converter that operates to convert the pump power of the desired wavelength s and ( = p-sp 0 / 1sp) differentially . Yb-doped MM fiber wavelength converter is formed by approximately the same noise level as low noise signal light , brightness (B) is substantially equal to n B (n is the number of HP laser diode , B is the brightness of each HP laser diode ) the output (P) is approximately equal to nPd (Pd output of the HP laser diode , n the number thereof) .
