Caption

Two-photon induced fluorescence in polycrystalline ZnSe while varying incident laser intensity at 775 nm (a) intense front face blue emission; (b) side view, I = 25 GW cm-2; (c) I = 4 GW cm-2; (d) I = 1.5 GW cm-2; (e) 1 GW cm-2. Fluorescence appears deeper in sample as incident intensity decreases.
