【 摘 要 】

We have obtained the single pulse laser oscillation with 400±10 ps pulse duration at 311 nm from LiLu0.7Y0.3F4:Ce3+crystal with 6 ns laser pump at 289 nm. We expect this due to passive Q-switch by means of pump induced color centers which absorb laser radiation and determine the intensity discrimination of laser pulses with contrast of about 1,8.
