摘要

摘要作者研究了飞秒辐射脉冲产生的激光等离子体中分子氮离子的激光特性。在氮气压力分别为 30 毫巴和 500 毫巴时，观察到波长分别为 391.4 纳米和 427.8 纳米的最大强度。辐射的发散度为数十 mrad，接近几何发散度。当透镜焦距从 15 厘米变为 40 厘米时，波长为 391.4 纳米的脉冲长度从 1.83 ps 变为 3.5 ps。

Lasing on Molecular Nitrogen Ions in Laser Plasma

Abstract

The authors study characteristics of lasing on molecular nitrogen ions in laser plasma created by a femtosecond radiation pulse. The maximum intensities at wavelengths of 391.4 and 427.8 nm are observed at nitrogen pressures of 30 and 500 mbar, respectively. The divergence of radiation is tens mrad and close to geometric. The pulse length at a wavelength of 391.4 nm varies from 1.83 to 3.5 ps upon changing the focal length of the lens from 15 to 40 cm.
