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488 nm蓝光和514.5 nm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1.19 V,透过的基本是488 nm谱线;电压为1.30 V透过的是514.5 nm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.
