Av. Podlipensky et al., Efficient laser operation and continuous-wave diode pumping of Cr2+: ZnSe single crystals, APP PHYS B, 72(2), 2001, pp. 253-255
Efficient continuous-wave laser operation of Cr2+:ZnSe was demonstrated wit
h an output power of 1400 mW at an absorbed pump power of 1900 mW from a Tm
:YAG laser. Under continuous-wave diode pumping at 1.54 mum an output power
of 15 mW was obtained from a Cr+2:ZnSe laser. Excited state absorption is
shown to be negligible in the pump and laser spectral region.
