摘　　要：以群速度色散展宽脉冲理论和基尔霍夫－菲涅耳积分为基础，合理地设计了一种紧凑有效的飞秒脉冲展宽器，不仅获得了较大的脉冲展宽比。A kind of compact and effective femtosecond pulse stretcher are designed reasonablely based on the Kirchhoff Fresnel integral. Not only a high stretching rate has been obtained, but also the spatial characteristics of the light beam through the stretcher has been reconstructed.
