摘要

本文针对CPA激光系统中二阶和三阶色散的补偿问题进行了理论研究。我们研究了由钛蓝宝石主振荡器产生的光脉冲沿拉伸-放大-压缩路径的传播。利用波动方程和色散平衡方程分析了各种ti -蓝宝石放大器结构。研究结果包括压气机长度偏差值和光脉冲在压气机输入衍射光栅上的入射角值。不同版本的放大器在光脉冲通过钛蓝宝石晶体的次数和晶体的几何轮廓上有所不同。所得结果列于表中。本研究对开发更高效的CPA激光系统具有重要意义。

SIMULTANEOUS COMPENSATION OF SECOND AND THIRD ORDER DISPERSION IN CPA LASER SYSTEMS

This paper presents a theoretical study aimed at solving the problem of compensation for second and third order dispersion in CPA laser systems. We study the propagation of light pulses generated by a Ti-Sapphire master oscillator along the path of a stretcher-amplifiers-compressor. The wave equation and dispersion balance equations are used to analyze various Ti-Sapphire amplifier configurations. The research results include the values of the deviation of the compressor length and the angle of incidence of the light pulse on the input diffraction grating of the compressor. Different versions of amplifiers differ in the number of passes of a light pulse through Ti-Sapphire crystals and in the geometric profile of the crystals. The results obtained are presented in the Table. This research is essential for the development of more efficient CPA laser systems.
