We report on high power. single-frequency operation of a compact Tm:Y2O3 ceramic laser in 2 μm spectral region employing a volume Bragg grating in a simple linear resonator to serve simultaneously as a resonator mirror and mode selector. The home developed laser quality Tm:Y2O3 ceramic sample has a Tm doped concentration of 2 at. % and pumped with a fiber coupled ... https://fitnessgravesyardes.shop/product-category/input-shaft/
