Popis:	Tunable distributed feedback (DFB) lasing output based on reflection grating configuration instead of the traditional transmission grating type was realized from rhodamine 6G (R6G)-doped ethanol and DCM-doped methanol. Pure gain coupling and additional index coupling were obtained in R6G-doped ethanol and DCM-doped methanol, respectively. The tuning which was independent on the refractive index of the lasing media went through all of the tuning data for the two cases. Dual-peak lasing emissions indicative of the existence of the index grating from the DCM-doped methanol were observed. The interval between the dual peaks increased as the increasing of the pump energy. The effect can be used to estimate the resonant nonlinear refractive index of luminescent materials.
