Abstract:

Laser performance of Аl₂0₃:Тi³⁺ crystal excited by electron beam with the current density at the crystal surface from 10 to 500 A/cm² at electron energy from 190 to 600 keV has been realized. Lasing has been achieved in the range from 0,76 to 0,85 μm, determined by the dielectric mirrors of the laser cavity. Intense crystal superluminescence is observed in the visible and near IR spectral region, mainly from 0,6 to 1,02μm. The analysis of the obtained results permits one to predict the construction of efficient and reliable lasers operating in a wide spectral range, based on Аl₂0₃:Тi³⁺ crystals excited with high-energy electrons. Such lasers can be used for solving a number of atmospheric optics problems.
