Intense isotropic laser emission from an optically pumped scattering g
ain medium has been used to induce isotropic lasing in an adjacent sca
ttering gain medium at a longer wavelength. The energy-transfer mechan
ism between the media involved has been studied with a simple model ba
sed on radiation-transfer theory. The applications of this effect for
wavelength-domain coding are also discussed. (C) 1996 Optical Society
