Влияние безызлучательных переходов на спектр генерации YAG:Nd-лазера

Влияние безызлучательных переходов на спектр генерации YAG:Nd-лазера

Abstract

It is usually accepted to describe the spectrum of the radiation YAG:Nd-laser using two amplification lines 1064.15 and 1064.4 nm that can not explain the generation on a wavelength of 1066 nm by heating the crystal more than 500 K. This article shows a stationary solution of the Tang-Statz-De Mars system taking into account the generation from two sublevels with seven lines for amplification. It is shown that the population of the sublevels of the multiplet 4 I 11 / 2 determines the dependence of the generation spectrum YAG:Nd-laser from crystal temperature. It is also shown that the distribution of populations of the sublevels of the multiplet 4 I 11 / 2 does not correspond to the Boltzmann distribution.

Обычно принято для описания спектра излучения YAG:Nd-лазера использовать две линии усиления 1064,15 и 1064,4 нм, что не позволяет объяснить генерацию на длине волны 1066 нм при нагреве кристалла более 500 K. В работе приведено стационарное решение системы уравнений Танга-Статца-Демарса, учитывающее генерацию с двух подуровней для семи линий усиления. Показано, что населённость подуровней мультиплета 4 I 11 / 2 определяет зависимость спектра излучения YAG:Nd-лазера от температуры кристалла и что распределение этой населённости не подчиняется распределению Больцмана.
