Fe²⁺: ZnSe laser pumped by a nonchain electric-discharge HF laser at room temperature

Abstract

The characteristics of a : ZnSe laser in a scheme with transverse pumping by a nonchain electric-discharge HF laser at room temperature are studied. Doping of ZnSe crystals with ions was performed by diffusion simultaneously through two surfaces under the conditions of thermodynamic equilibrium. It is found that the : ZnSe laser pulses are modulated by short spikes ( at half maximum at low pump energies), whose number decreases and modulation depth increases as the pump energy decreases to a threshold value. A laser pulse energy of is achieved at a pulse duration at half maximum of (at high pump energies); the possibility of a further increase in the energy of : ZnSe lasers pumped by nonchain HF lasers is discussed.
