【Abstract】 The technique of optical parametric chirped pulse amplifier proposed recently is introduced, and some characteristics such as phase match angle, gain and bandwidth are analyzed taking LBO crystal as an example. In addition, the dependence of the gain varying with length of the crystal is studied, and the transforms of the pulses after amplification with sech 2 and Gauss shapes are given.更多还原
