974 1030 HIGH POWER FIBER PUMP SOURCE WITH HIGH BRIGHTNESS LOW NOISE OUTPUT IN ABOUT 974-1030NM WAVELENGTH RANGE

摘要

And the invention of the high-power high-brightness pump source for the low noise of about 974nm to smoothing in the desired wavelength within the wavelength range of 1030nm and multimode ( "MM") for emitting a signal light of a low-noise seed source, the sub-pump wavelength (λ _sp) in a plurality of high power ( "HP") is configured to have the MM Yb fiber wavelength converter for the emission of the semiconductor laser diode converting the pump output at the desired wavelength _{(λ p), △ λ =} λ p - λ sp 0 / the _1λ sp. Yb- doped MM wavelength converter is configured to have the same noise level, and the n × B is substantially equal to the brightness ( "B") with a low-noise signal and the substantially light, n is the number of HP semiconductor laser diode, B are each HP is the brightness of the laser diode, the output power ( "Po") is substantially the same as nPd, and Pd is the power of each laser diode and HP, n is the number of HP laser diode.
