Безрезонаторная Генерация На Ионах Молекулярного Азота В Воздушной Лазерной Плазме

Abstract

In this work, the results of investigation of temporal and spectral lasing characteristics on the first negative transition В – X of molecular nitrogen ions in air laser plasma are presented. Pumping was performed by the emission with central wavelength of 950 nm, 60 fs duration, and energy of 10 mJ. The active medium parameters are analyzed and possible mechanism for the formation of picosecond duration of radiation pulse is discussed.
