【 摘 要 】

We show that the LiY0,3Lu0,7F4:Ce3+and LiY0,3Lu0,7F4:Ce3++Yb3+crystals are promising active media of UV spectral range with low-threshold lasing (30-90 mJ/cm2). Due to crystal-chemical approach (additional doping by ions Yb3+) we obtained the effect of suppression of spurious photodynamic processes. The active medium LiY0,3Lu0,7F4: Ce3++ Yb3+combines properties of saturable amplifier and oscillator with small saturation energy, and promising to generate pulses of ultrashort duration in the UV spectrum.
