Low threshold YSGG:Cr:Er laser for the 3-μm range with a high pulse repetition frequency
A laser emitting at the wavelength of 2.79 μm was constructed using an yttrium scandium gallium garnet containing chromium and erbium, and the threshold of this laser did not exceed 2 J. This made it possible to achieve an average output power of 0.7 W at a pulse repetition frequency of 100 Hz.
