| 摘 要： | 用准连续６０Ｗ的二极管激光列阵侧面泵浦“之”字形Ｎｄ：ＹＡＧ板条激光器，当泵浦功率为４５Ｗ，脉宽为４００μｓ时，得到３．５ｍＪ的激光输出。用ＫＤ＊Ｐ电光开关调Ｑ，得到１８ｎｓ（ＦＷＨＭ）、２ｍＪ的脉冲激光输出，用ＫＴＰ晶体作腔内倍频，得到１５ｎｓ、０．８５ｍＪ的二次谐波激光输出。在腔内无调Ｑ元件且腔长小于５ｃｍ时，于近阈值处得到单频绿光输出，而当泵浦功率稍大，腔内有数个纵模振荡时，观察到激光的反相态，并用数值模拟的结果对此作了解释。

| Abstract: | A Nd:YAG laser was side pumped with laSer-diode-array of 45 W Q-cw(400 μs) output. This laser provides 3.5 mJ output at 1064 nm for free runing oscillation, and 0.85 mJ at 532 urn for Q-switched operation with pulse. width of 15 ns. Removing the Q-switch away, and shortening the cavity optical length to less than 5 cm, a single longitudinal mode of 532 nm laser was observed near threshold. Increasing the pumpPower somewhat, we have observed the antiphase laser output. |
