Growth and Device Performance of RTP Electro-Optical Crystal
摘要
Abstract
Rubidium titanyl phosphate(RTP)is an electro-optical(EO)crystal with excellent comprehensive performance,which has the advantages of high electro-optic coefficient,low half-wave voltage,high laser damage threshold as well as compact device,strong environmental adaptability,etc.These characters make it become a new generation of EO materials,suitable for use as EO switches,modulators,and other EO devices.The development of laser systems urgently requires high-performance EO crystals for higher power,higher repetition rate,and narrower pulse width lasers.In this paper,the growth system with high[Rb]/[P]molar ratio was chosen,and high-quality RTP crystal was successfully synthesized by the top seeded solution growth method.Relevant properties of crystal or device were tested,containing the optical uniformity,repetition rate,insertion loss,extinction ratio and laser damage threshold.The results show that,the optical homogeneity of sample is 7.3×10-6 cm-1,repetition frequency of 501 kHz,insertion loss of 0.49%,extinction ratio of 31.57 dB,and laser damage threshold of 856 MW/cm2.关键词
