Compare of characteristics between Martinez and Offner stretchers used in chirped pulse amplifier
用于飞秒脉冲放大器的马丁内兹展宽器与欧浮纳展宽器性能比较

In this paper, the characteristics and range of application of the Martinez and the Offner stretchers in a chirped pulse amplifier system is analyzed theoretically for a multiple-pass amplifier and a regenerative amplifier respectively. The Martinez stretcher can completely compensate the dispersion introduced either from a multiple-pass amplifier or from a regenerative amplifier within a certain bandwidth. In a regenerative amplifier, if it is necessary to obtain broader pulses, the compact Offner stretcher can be applied.
