The Fabrication and SHG Test of QPM Periodically Poled KTiOPO

The Quasi-phase-matching periodically poled flux-grown KTP by high electrical field method is researched. A 8X5X 1mm、, A=9.0|im PPKTP wafer is successfully fabricated for the first order QPM SHG. The interactive length of the sample is about 3mm. The SHG scheme of Nd:YAG at 1064nm tested that the ou
