飞秒激光宽频干扰导弹技术

摘要

介绍了飞秒激光在介质中的非线性传输现象和机理,论证利用飞秒激光在空气和光电窗口介质中非线性传输形成的宽光谱辐射干扰各类光电制导导弹的可行性,实验研究了飞秒强激光通过空气、K9玻璃、石英、MgF等介质时的辐射特点和规律,说明利用飞秒强激光直接攻击导弹窗口将更有效.%Nonlinear propagation phenomena and mechanism of femtosecond laser pulse transmitting in optical medium are introduced. White-light continuum generated in femtosecond laser pulse nonlinearly transmitting in air or missile seeker window may be useful for missile countermeasure applications, which has been observed experimentally in air, K9 glass, quartz and MgF.
