Paper Abstract

The author for the first time develops the elementary theory of laser on vibronic crystal with electron excitation allowing to describe theoretically the main generation characteristics of laser electron -- oscillatory and recombination transitions in a dielectric ion crystal of a vibronic type, pumped both by electron, and combined (optical and electron) technique. On the basis of the mentioned above elementary theory the estimations of main generation characteristics for laser transitions in a crystal Al2O3:Ti3+, excited by a pulsed electron beam are carried out. In particular, there are determined optimum (for generation energy in a pulse) parameters of pulsed electron excitation for laser transition 2E - 2T2g of an ion Ti3+: electron energy in a beam 200 - 300 keV, current density 1 kA/cm2. Thus the wavelength tunable band of laser radiation reaches from 0.6 microns up to 1.1 microns, and under certain conditions -- from 0.55 microns up to 1.3 microns. The basic opportunity of simultaneous laser generation on the recombination transition bands from 0.29 microns up to 0.45 microns is discussed. The examples of laser complexes with new architecture are given which by numerical modeling allow to predict an opportunity of laser generation energy in a pulse up of to 1 J and average output power up to 100 W and more inside a wavelength tunable range approximately from 0.55 microns up to 1.3 microns, that can be of interest for a wide range of laser radar technologies.
