In the opo theory , the principium of the optical parametric oscillator is explained 在opo理论方面,分析了opo的工作原理。
This thesis is devoted to various studies involving quasi - phase matched optical parametric oscillator 为此,在本文中,我们对准位相匹配的光学参量振荡器进行了一系列的研究。
With a wide - spectrum tunable output , optical parametric oscillator ( opo ) extends the laser wavelength and meets diversified needs 光学参量振荡器( opo )可以产生宽范围可调谐激光输出,它的出现拓宽了激光波长,使之可以满足各种应用需要。
At present , ktp has been widely used in second harmonic generation ( shg ) , sum ( difference ) - frequency mixing , optical parametric oscillators ( opo ) and optical parametric amplification ( opa ) 目前, ktp已作为一种商业化的晶体广泛应用于中小功率固体激光器的倍频( shg ) 、和(差)频、光参量振荡( opo )和放大( opa )等。
In addition , quasi - phase - matched materials is being used in optical parametric oscillator widely . periodically poled nonlinear crystals are of particular advantage for realizing efficient optical parametric oscillators 另外,利用ppln制成的光参量振荡器产生的红外波段光源,在军事对抗、大气环境检测、医学以及光谱学等领域都有十分重要的应用价值。
