We propose a new method for the synthesis of arbitrary temporal output pulse profiles by using a birefringent laser pulse shaper. This shaper contains a series of $ N $ birefringent crystals placed between input and output polarizers. The synthesis method starts with the linear time-invariant system theory to determine the optimal amplitudes of the replica pulses at the output polarizer and the time delay between them, and then uses the temporal Jones matrix formalism to obtain the angle of each crystal. The design procedure is demonstrated for an eight-stage birefringent laser pulse shaper. Several examples of predefined output pulse profiles are given to show the potential of the proposed birefringent laser pulse shaper.

双折射激光脉冲整形器的广义时间合成方法

我们提出了一种通过使用双折射激光脉冲整形器来合成任意时间输出脉冲轮廓的新方法。该整形器包含一系列放置在输入和输出偏振器之间的$ N $双折射晶体。合成方法从线性时不变系统理论开始，确定输出偏振器处复制脉冲的最佳振幅以及它们之间的时间延迟，然后使用时间琼斯矩阵形式来获取每个晶体的角度。演示了八级双折射激光脉冲整形器的设计程序。给出了预定义输出脉冲轮廓的几个示例，以显示所提出的双折射激光脉冲整形器的潜力。
