Measurements carried out on a 50 Hz a.c. excited He−Cd laser operating at 4416 Å indicated the possibility that two processes are involved in the excitation mechanism for this laser transition. It is suggested that the two processes are (1) Penning ionization of neutral Cd atoms by collisions with He metastables, and (2) electron — Cd ion collisions. The theory developed on the basis of the suggested excitation mechanism gives quantitative data on operation parameters of the laser.

О механизме возбуждения и рабочих параметрах лазера 4416 Å He−Cd


Измерения, проведенные с He−Cd лазером возбужденным переменным током в 50 Гц в рабочем состоянии при 4416 A, показывают на возможность, что механизм возбуждения для этого лазерного перехода складывается из двух процессов. Согласно авторам этими двумя процессами являются пеннингова ионизация нейтральных атомов Cd путем столкновений с метастабильными атомами He и столкновения электрон-ион Cd. Теория, разработанная на основе изложенного механизма возбуждения дает количественные данные о рабочих параметрах лазера.
