摘要
In this paper we report a compact and robust regenerative amplifier developed as the pump laser for a high repetition rate terahertz parametric amplifier.With properly chosen pump source and carefully designed cavity,Nd∶YVO4 crystal,and laser beam collimator,a maximum output pulse energy of 480μJ has been achieved at the repetition rate of 10 kHz.The output laser has a nearly Gaussian transverse profile and a narrow bandwidth of 0.2 nm.Longterm monitoring shows an root mean square power fluctuation of about 1%.These characteristics satisfy all requirements for high repetition rate terahertz parametric amplifier.
