optical parametric amplifier meaning in English

光参量放大器
光参数放大器

Two kinds of bright epr entangled beams were experimentally generated by means of nondegenerate optical parametric amplifier ( nopa )
利用非简并光学参量放大器从实验上产生了两种明亮epr纠缠态光场。
We use the laser output ( 320 nm , 200 fs ) of optical parametric amplifier ( opa ) in < wp = 5 > an active passive mode - locked femtosecond ti - sapphire laser operating at a repetition rate of 1khz as a exciting resource to develop optically pumped stimulated emission of zno thin films . when rectangular stripe laser irradiates thin films , optical resonant cavity is naturally formed between two nanocrystallites along with the rectangular laser stripe and planar weveguide confines the light scattering
利用飞秒激光器作为光泵浦激发光源，研究了氧化锌薄膜的光泵浦受激发射，当条形光斑辐照薄膜样品时，将沿着光斑条由氧化锌纳米晶面自然地形成光学谐振腔，由于平面介质波导结构限制光散射，所以成功地观测到二氧化硅衬底上的纳米氧化锌（ zno ）薄膜的紫外受激发射。
