Abstract:
Stimulated emission was observed from solutions of derivatives of aza-1,2,4-triazine excited with nitrogen laser ($\lambda=337,1$ nm) nanosecond pulses. The active substances were synthesized by an experimental laboratory technology. Preliminary luminescence spectra as well as energy, time, and other characteristics of the radiation were obtained for the compound designated as $CX-10$, typical of several investigated dyes. The experimental methods used to observe stimulated emission are described.
