摘要
FIELD: lighting.;SUBSTANCE: heavy-duty low-noise pumping source contains inoculating source, which generates low-noise light signal, plurality of powerful semiconductor laser diodes, joined for auxiliary pumping and alloyed by Yb multimodal fibre wavelength converter for auxiliary pumping. At that, pumping radiation has level of noise, identical to level of noise of low noise light signal, brightness is equal to n×B, where n is number of powerful semiconductor laser diodes, and B is brightness of each powerful laser diode, output power (Po), in fact, equal to nPd, where Pd is power of each powerful laser diode, and n is their number.;EFFECT: technical result consists in elimination of non-linear effect, which limit beam amplification and quality.;20 cl, 5 dwg
