| 摘 要： | 报道了一种利用复合腔进行腔内和频的589nm激光器.激光器由两个子谐振腔组成.在两个子谐振腔中,分别利用两个激光二极管(LD)抽运Nd∶YAG晶体和Nd∶YVO4晶体,并分别选择1319 nm波长(对应Nd∶YAG晶体的4F3/2→4I13/2跃迁)与1064 nm波长(对应Nd∶YVO4晶体的4F3/2→4I11/2跃迁)振荡进行和频.通过谐振腔的优化设计,实现了腔内两个波长较好的模式与增益匹配.在两个子腔的交叠部分,利用BiB3O6(BIBO)晶体Ⅰ类临界相位匹配进行腔内和频,得到和频激光输出.当Nd∶YAG与Nd∶YVO4晶体上抽运功率分别为750 mW和600 mW时,获得了24 mW,589 nm黄橙激光输出.该输出激光光束质量好、噪声低.

| Abstract: | A compact continuous wave (CW) 589 nm laser is reported by intracavity sum-frequency mixing in a composite cavity. The laser has two sub-cavities. Nd:YAG crystal and Nd:YVO4 crystal were pumped by two laser diodes respectively in the two sub-cavities. In the two cavities wavelengths of 1319 nm from Nd:YAG (corresponding to the 4F3/2-4I13/2 transition) and 1064 nm from Nd:YVO4 (corresponding to the 4F3/2-4I11/2 transition) were chosen to be mixed into 589 nm laser. Through designing of the cavity, the optimum matching of modes and gains for the two wavelengths was obtained. In the overlapping of the cavities, sum-frequency mixing was generated with a type I critical phase matching BiB3O6 (BIBO) crystal. A stable laser output of 24 mW at 589 nm with low noise was obtained at the incident pump power of 750 mW for the Nd:YAG crystal and 600 mW for the Nd:YVO4 crystal. |
