title: Investigation of Cr:Tm:Er:YAG laser crystals in a resonator with various degrees of spectral selectivity.
abstract: It has been established that Tm(3+) ions do not prevent multiple-wavelength oscillation in Cr:Tm:Er:YAG laser crystals inserted inside of the completely nonselective mirror resonator. The output mirror spectral selectivity needed for single-wavelength oscillation at 2.697 mum for a considerable excess of pumping energy over the threshold has been determined experimentally. It has been shown that Tm(3+) optimum concentration in the crystals could be determined correctly in the described resonator scheme.
