摘　　要：以PPLN、PPMgLN、PPKTP等为代表的周期极化工艺的成熟,极大地促进了准相位匹配技术的发展,拓宽了非线性晶体应用范围,大大提高了频率转换效率。周期极化晶体与其它非线性晶体结合,利用倍频、差频、混频、0PO等技术是实现激光波长拓宽的一种非常有效的手段。本文阐述了QPMPPLN在蓝绿激光器及中红外OPO的应用进展,展望了PPLN的应用发展趋势。The development of period-polarization technology in PPLN, PPMgLN, PPKTP crystals, which greatly pro- moted the quasi-phase-matching technology, and broadened the scope of application of nonlinear crystal, greatly im- proving the efficiency of frequency conversion. Frequency doubling, difference frequency generation and OPO using periodically poled nonlinear crystals combined with other nonlinear crystals was a very effective means to broaden the wavelength of the laser. The application of QPM PPLN to the blue-green lasers and mid-infrared OPO were introduced, and the development trend of PPLN application was prospected in the paper.
