| 摘 要： | 随着2.94 激光在医学中的应用日益广泛,控制工作激光参数提高医疗安全性能显得尤为重要,因此对工作的激光进行调Q是很有必要的。文中介绍了利用双布儒斯特角切割的LiNbO3晶体作为电光Q开关的Er:YAG调Q激光器,在工作频率5Hz,脉冲泵浦能量92J条件下,获得了脉宽103 ~110ns,能量达到87mJ的调Q脉冲激光输出。并分别在静态和调Q模式下对龋牙进行了窝洞制样,利用扫描电子显微镜对样本扫描,对比显示调Q激光制样的效果更好。

| Abstract: | With the extensive application of 2.94 laser in medicine, the control of laser parameters are particularly important to improve medical safety, therefore, Q-switched operation of Er:YAG laser is necessary. With LiNbO3 crystal cut at Brewster’s angle acted as electro-optical Q-switching of the Er:YAG laser, at 5Hz repetition rate and pump energy of 92J, giant pulses of 103 ~ 110ns duration and 87mJ energy were obtained. A free-running and Q-switched pulsed laser was used for the cavity preparation experiments of the dentine respectively. Using scanning electron microscopy, the samples showed that Q-switched laser is more efficient. |
