| 摘 要： | 980 nm垂直腔面发射激光器(VCSEL)采用直接倍频和在复合腔中倍频两种方式实现了490 nm蓝光输出。整形采用0.23p@980nm的自聚焦透镜(GRIN lens),倍频晶体选择非线性系数相对较大、允许角相对较宽的LBO晶体。在VCSEL输出功率为530 mW时,选取透过波长为980 nm、长度为0.23 pitch的自聚焦透镜整形,倍频晶体选择2 mm×2 mm×5 mm的LBO晶体,输出了50 μW的490 nm蓝光,在增加了曲率半径R=50 mm的外腔镜后得到了70 μW的490 nm蓝光。 |

| Abstract: | A 980 nm vertical cavity surface emitting(VCSEL) laser realizes frequency doubled by directly doubling and compound cavity doubling and obtains 490 nm blue laser. GRIN lens are used for shaping beam and LBO crystal is employed for secondary harmonic generation(SHG). In the experiment, the output power of the fundamental frequency laser is 530 mW,Gauss beam is adjusted by one GRIN lens with a length of 0.23p@980 nm and a LBO crystal with dimensions of 2 mm×2 mm×5 mm. And 490 nm blue beam of 50 μW is obtained. By adding an external cavity mirror with a radius curvature of 50 mm,the output power of 490 nm blue beam is increased to 70 μW. |
| Keywords: | vertical cavity surface emitting laser direct frequency doubling compound cavity LBO crystal GRIN lens secondary harmonic generation |
