【Abstract】 A periodically poled KTiOPO4(PPKTP) for second harmonic generation(SHG) with 9 μm period,8 mm length,3 mm width and 1 mm thickness has been successfully fabricated by applying an external electic field of high pulsed voltage.During the program,the real time monitoring measures such as electro-optical effect method,second harmonic generation two-dimensional method were used.13.5 mW of 532 nm second harmonic generation green light was obtained pumped by 1 W,1064 nm fundamental wave.The single-pass second harmonic generation conversion efficiency was 1.35% and the normalized conversion efficiency was 1.69% /(W·cm),which was close to the maximal theoretic value.更多还原
