摘要 本文介绍了双波长晶体激光器的概况,重点描述了我们在双波长晶体激光器方面的研究工作。这些工作如下:建立了多波长激光器的振荡条件,用它分析,比较了Nd:YAG,Nd:YLF,Nd:BEL和Nd:YAlO3等晶体实^4F3/2-4I11/2和^4F3/2-^4I13/2跃迁双波长激光的可能性,分析表明上述晶体均能实现脉冲双波长激光,但只有Nd:YAP晶体能实现连续双波长激光运转。根据这判断,我们利用Nd The survey of dual wavelength crystal lasers is introducted in this paper. Our research results on dual wavelength crystal lasers are described mainly. These are as follow:oscillation condition of a simultaneous multiple wavelength laser has been established and used to analyze the possibility of simultaneous oscillation in various neodymiumhost crystals,such as Nd : YAG, Nd : YLF, Nd : BEL and Nd': YA103(YAP) crystals at transitions from ~4F_(3/2)—~4I_(11/2) and ~4F_(3/2)—~4I_(13/2). It shown that this kind of laser can be realized in all the described crystals in a pulsed state. In general, continuous wave operation, however, can only be achieved in Nd : YAP crystal. On the basis of these results, the CW dual wavelength crystal lasing has been achieved for the frist time by using Nd : YAP crystal.The output power of 1079.5 nm and 1341.4 nm was 23.9 W and 25. 4 W respectively.The Nd : YAG and large energy Nd : YAP dual wavelength pulsed lasers were also acquired. The experimental results show that the temporal and spatial overlops of both beams were quite good for both lasers. In addition, we has obtained 1655 nm and 1663 nm dual wavelength and 2711 rim, 2730 nm and 2795 nm three wavelength Er : YAP lasers.
