Low-Order Harmonic Generation of Laser Radiation in Various Media

摘要: One of the main objectives optics and quantum electronics is a search new sources coherent radiation in different spectral ranges. A commonly used technique frequency conversion (FC) polarized well-developed laser via nonlinear optical processes. Presently, along with widely crystalline media, gases, plasma plumes, nanoparticles, reflection from surface have been successfully demonstrated as attractive media for harmonic generation (HG) radiation. Gaseous are subject great interest last three decades due to their wide applications media. They permit convert into ultraviolet (UV), extreme (XUV), infrared (IR) ranges using parametric Conversion efficiencies attained such way favour create XUV intensities higher than that synchrotron Another important application HG gases attosecond pulses.
