We demonstrate a temperature tunable infrared optical parametric oscillator (OPO) based on periodically poled LiNbO3 (PPLN) pumped by an acousto-optically Q-switched cw-diode-end-pumped Nd:YVO4 laser with the signal output from 1.48μm to 1.54μm by tuning the work temperature from 60℃ to 250℃ and the maximum average signal power (1500nm) of 137mW. We report the demonstration of the sum frequency of the pump and idler in a single-grating PPLN crystal. In addition, we present the theoretical analysis of the signalwavelength change rate with the changing temperature for a quasi-phase matching OPO, which is in good agreement with our experimental results.

中期规划配套短期措施 国务院日前发布了《国内贸易发展“十二五”规划》（以下简称《规划》），这是改革开放以来我国第一部国家级的内贸发展专项规划。按照此规划，到2015年社会消费品零售总额将达到32万亿元，年均增长15%。 个人认为，在当前经济低迷的背景之下，《规划》的出台适时给市场注入了一些信心，其中不乏亮点；但由于《规划》实施比较缓慢且受制于多重因素，建议在这一中期《规划》下，配套一些行之有效
