The Efficiency of Continuous Output of Some Titanium-Doped Gem-Crystal Lasers Has Exceeded 1 W

Abstract

By use of the Induced Furnace Up-pumping Method (IFUS) developed by ourselves, a new technique enables us to grow a titanium-doped gem crystal which can emit pulses in the forward as well as in the backward direction in the preparation of a continuous laser beam transmission. Since December of 1991 after it first appeared in our country, the continuous transmission of a titanium crystal laser (1) with hydrogen ion laser-pumping has reached a laser output efficiency of 303 mW and the threshold efficiency of 1.5 W. Recently, the crystalline mass grown by us has made another step forward to form a continuously lasing apparatus which acquired new progress in the output efficiency and resonance-harmonization capability.
