LiNbO_3晶体压电应变光束调制器及激光锁模器解析

ANALYSIS ON LiNbO_3 CRYSTAL PIEZOELECTRIC RESONATORAND LASER MODE LOCKER

对轴切LiNbO_3晶体压电应变光束调制器(PESOM)及其作为激光锁模器的特性进行了详细解析。证明x切板共振器是作为激光锁模器的最佳运用方式,而y或z切板将不可避免地具有同时损耗调制和频率调制的双重作用,因而原则上不宜用于诸如激光锁模器这样的场合。

Axis-cut LiNbO_3 crystal piezoelectric strain optical modulators (PESOM)and its properties when they used as laser mode lockers are analysed in detail. We have proved that x-cut plate is the best form used for laser mode locker. And y-cut or z-cut plate will result in loss modulation and frequency modulation at the same time, so in principle they are not suitable for using as laser mode locker operating at steady state.
