Use of electrochemical reaction products in the active media of dye lasers to extend the tuning range of the stimulated emission spectra

Investigations were made of the spectral, temporal, energy, and angular characteristics of the stimulated emission from dye lasers pumped with a pulsed nitrogen laser and undergoing electrochemical reaction in the solution. It was established that dye lasers with electrochemically controlled radiation parameters exhibited many valuable advantages. Stimulated emission was possible over a broader (by a factor of 1.5–2) spectral range. Passage of an electric current increased negligibly the optical inhomogeneity of the laser solution and the divergence of the radiation during operation. Passage of a current through some solutions stabilized the laser radiation output energy.
