Ultra-short pulses UV lasing in multifunctional Ce:LiY 0.3 Lu 0.7 F 4 active medium

The single pulse laser oscillation with 400 ± 10 ps pulse duration at 311 nm from LiY0.3Lu0.7F4:Ce3+ crystal was obtained from intracavity loss modulation via pump-induced color centers bleaching. Modulation of average losses is regulated via color centers concentration that determines the multifuncionality of solarizable LiY0.3Lu0.7F4:Ce3+ active medium.
