| 中文摘要 | 对激光二极管(LD)端面抽运的Nd:YAG晶体产生946 nm激光输出的热效应及输出特性进行了实验对比。实验测量了晶体的端面温度以及热焦距,当吸收抽运光功率达到10 W时,掺杂原子数分数1.0%的端帽键合Nd: YAG晶体端面温度为25.9 ℃,约为相同掺杂浓度下普通晶体的1/3。且相同条件下,端帽键合Nd:YAG晶体能有效缓解热透镜效应。利用波片补偿电光晶体热退偏的方法,实现了频率为1 kHz电光调Q 946 nm激光输出。在抽运功率为10.4 W时,使用掺杂原子数分数为0.5%的端帽键合Nd:YAG晶体作为增益介质,获得最大输出功率为311 mW,脉冲宽度为17 ns的电光调Q 946 nm激光输出,功率不稳定性为2.7%。最大输出功率分别是同等条件下使用掺杂原子数分数1.0%的端帽键合Nd:YAG晶体的2倍以及普通Nd:YAG晶体的3倍。 |
| 英文摘要 | Comparative studies on the thermal effect and laser performance of diode-end-pumped Nd : YAG crystals at 946 nm are presented. The temperature of end surfaces and thermal lensing of crystals are measured. When the absorbed pumping power reaches 10 W, the end surface temperature of the atomic fraction of 1.0% doped composite crystal is 25.9 ℃ which is only 1/3 of that of 1.0% non-composite crystal. Morever, the composite crystal can relieve the thermal lensing effect under the same condition. A compensation of the thermal effects in electro-optical crystals is achieved by employing a quarter-wave plate, which allows for the production of an electro-optically Q-switched 946 nm Nd : YAG laser at 1 kHz. A maximum output power of 350 mW and 17 ns pulse duration laser is achieved with the atomic fraction of 0.5% doped composite crystal under the incident pumping power of 10.4 W. The power stability is 2.7%. The maximum output power is more than three times higher than that of a non-composite crystal and two times than that of a atomic fraction of 1.0% doped composite crystal. |
