我们报道了用飞秒激光用双线方法在周期性极化铌酸锂上书写的热稳定光波导。1064 nm和532 nm的基频光和次谐波光都具有低阻尼损耗。在10毫米长的样品中，转换效率达到58%。
We report on thermally stable optical waveguides written in periodically poled lithium niobate with a femtosecond laser using a two line approach. Both fundamental and second harmonic light at 1064 and 532 nm are guided with low damping losses. In a 10-mm-long sample a conversion efficiency of 58% was achieved.
