Experimental research on frequency doubling in periodically poled KTiOPO_4 waveguide fabricated by femtosecond laser

  • 摘要: 在PPKTP晶体上进行了飞秒激光刻写波导的实验研究,优化了c-切PPKTP晶体中写制二型波导的工艺参数.当波导长度为10 mm,宽度为14.5μm,准相位匹配波长为1064nm时,实现了单模传输.利用该波导对调Q Nd:YAG激光进行了准相位匹配倍频实验,实现的二次谐波转换效率为39.8%.
    Abstract: We present in this paper the fabrication and characterization of type Ⅱ waveguide in c-cut periodically poled KTiOPO_4 crystal The wavegnide was fabricated by using a femtosecond laser, and the fabrication process was optimized. In our experiments single mode propagation was observed at optimal wavegnide width of 14.5 μm and quasi-phase matching wavelength of 1064 nm. The second-harmonic conversion efficiency of 39.8% can be achieved.
