| 摘 要： | 采用中频感应加热提拉法生长出具有可饱和吸收性质的四价铬离子掺杂钇铝石榴石晶体（Ｃｒ４＋ＹＡＧ），实现了连续ＮｄＹＡＧ激光的被动调Ｑ高重复率脉冲输出。报道了Ｃｒ４＋ＹＡＧ晶体存在一种光致附生损耗机制，并讨论了其对于调Ｑ特性的重要影响。

| Abstract: | A high quality single crystal of Cr4+:YAG, grown in our laboratory by the Czochralski method was used in the Q-switching experiment successfully for a Nd:YAG laser, which provided laser pulses of 800 ns in duration, a repetition rate of 3～13.33 kHz and an average pulsed output power higher than 13 W. The jitter of the Q-switched laser is also discussed in this paper. A possible mechanism was suggested and indicated that a more stable output of Cr4+ :YAG Q-switched laser would be achieved by further improving the crystal qulity in the growth and post-treatment processes. |
