| 摘 要： | 从理论和实验上证明了液晶调谐滤光片可用于复色激光器中提取所需要的谱线 ,从而避免多级双折射滤光片的使用。对Ar+激光器中最强的两条谱线 488nm蓝光和 5 14 5nm绿光进行测试 ,用较低的调谐电压即可提取所需要的谱线 ,当两谱线经过以E70为材料的液晶调谐滤光片时 ,液晶盒上所加电压为 1 19V ,透过的基本是 488nm谱线 ;电压为 1 30V透过的是 5 14 5nm谱线。

| Abstract: | It is proved from the theory and experiment that the liquid crystal tunable filter can be used to select some desired wavelength from a multiline laser. With the tunable liquid crystal filter outside the Ar + laser, the beam of 488 nm under voltage of 1.19 V and 514.5 nm under voltage of 1.30 V can be achieved, respectively. |
