Jw. Zhang et al., ENHANCEMENT OF THE EXPONENTIAL GAIN COEFFICIENT AS A RESULT OF THE LIGHT-FANNING EFFECT IN THIN DOPED LINBO3 CRYSTALS, Optics letters, 18(17), 1993, pp. 1391-1393
The enhancement of the exponential gain coefficient of two-beam coupli
ng in several thin samples of doped LiNbO3 crystals is reported. The m
echanism is analyzed by light crawling that originates from the light-
fanning effect. Some experimental results to support the explanation a
re presented.
