论文摘要
提出了一种基于光栅的光脉冲压缩机的新型设计。提出的压缩机提供了较大的组延迟分散体，同时保持压缩机线性尺寸较小。所提出的压缩机的设计基于传统的Treacy压缩机，其直接修改是在压缩机的光栅之间插入两个镜头。这种简单的交替旨在实质上增加压缩机的群延迟分散，或者降低压缩机的大小，同时保持其组延迟分散。增强压缩机的理论描述已在近似近似中开发。已经构建了一个详细的数值模型，以更准确地计算压缩机参数。这些理论研究表明，与标准的Treacy压缩机相比，增强的光学压缩机可显着增加组延迟分散体。
A novel design of a grating-based optical pulse compressor is proposed. The proposed compressor provides a large group delay dispersion while keeping the compressor linear size small. The design of the proposed compressor is based on a traditional Treacy compressor with a straightforward modification of inserting two lenses between the compressor's gratings. This simple alternation aims to substantially increase group delay dispersion of the compressor or alternatively to decrease the compressor size while maintaining its group delay dispersion. A theoretical description of the enhanced compressor has been developed in the paraxial approximation. A detailed numerical model has been built to calculate the compressor parameters more accurately. These theoretical studies have revealed that the enhanced optical compressor provides a significant increase in the group delay dispersion compared to a standard Treacy compressor.
