【摘要】 为获得高亮度低发射度的电子束,研制高重复频率高平均功率的光阴极驱动激光系统非常关键。利用光纤激光技术,设计了100 MHz和1.3GHz的激光系统。激光系统为全光纤结构,采用了掺镱光子晶体光纤作为放大器增益介质。在初步验证实验中,红外激光输出27 W,倍频后绿光达到6 W。更多还原

【Abstract】 It is difficult to find commercial laser products meeting the requirements of ERL photocathode gun.Therefore,a drive laser system is being developed at Institute of High Energy Physics(IHEP),which comprises two kinds of laser seeds,1.3GHz and 100 MHz at repetition rate.Fiber amplifiers were being constructed and a test system was set up.The output power of the main amplifier can reach up to 27 W.With a 5-mm-long LBO crystal,the green second harmonic laser of 6W was achieved in the preliminary validation experiment.更多还原
