Abstract

An ultrafast pulse shaper, capable of both phase and amplitude shaping, is constructed using a single high-resolution liquid crystal phase mask. The shaper is calibrated with an inline spectral interferometry technique. Amplitude shaping is accomplished by writing to the mask a phase grating, whose period is smaller than the spectral focus, diffracting away selected frequencies in a controllable manner.

摘要

一种能够同时进行相位和幅度整形的超快脉冲整形器，是使用单个高分辨率液晶相位掩模构建的。该整形器采用在线光谱干涉测量技术进行校准。幅度整形是通过在掩模上写入一个周期小于光谱焦点的相位光栅来实现的，该光栅以可控方式衍射掉选定的频率。
