Abstract

Radiation spectrum broadening upon the generation of the second harmonic in nonlinear crystal is studied. Spectrum broadening is ensured in one or two nonlinear KDP crystals detuned by the phase matching angle or with chirped pulses of pump radiation. Possibility of the spectrum width doubling of the second harmonic is shown.

二次谐波产生的频谱轮廓扩大

摘要

研究了非线性晶体中二次谐波产生时的辐射谱展宽。在通过相位匹配角或泵浦辐射的chi脉冲失谐的一两个非线性KDP晶体中，可以确保频谱加宽。显示了二次谐波频谱宽度加倍的可能性。
