Laser-related spectroscopy of KY3-xYbxF10:Ce3+ crystals

Here spectral-kinetic properties of Ce3+ ions and UV pumping induced color centers in KY3FI0 (KYF) crystals are reported and discussed. The efficiency of crystal-chemical approach of UV pumping induced solarization processes inhibition in these crystals was shown. Laser oscillation was achieved on the Ce:KYF crystals which were considered earlier as unpromising as active medium due to its photochemical instability.
