Efficient difference-frequency generator utilizing an Al2O3:Ti3+ laser

An analysis was made of a highly efficient source of coherent radiation utilizing an Al₂O₃:Ti³⁺ crystal laser and a nonlinear LiIO₃ crystal, emitting in the 0.34–2.3 μm spectral range. It incorporated a specially developed Al₂O₃:Ti³⁺-crystal laser bichromator in which self-synchronization of both channels was achieved. Particular attention was paid to the kinetic characteristics of the Al₂O₃:Ti³⁺ crystal laser. It was shown that, in principle, the spectral range could be extended to the ultraviolet and the infrared.
