High order Bragg scattering (M = 2 and M = 3) operations of the distributed feedback dye doped sol-gel silica lasers are achieved using the second harmonic output of a Nd:YAG laser as the pump. Laser linewidth of less than 0.06 nm and conversion efficiency of 0.7% for M = 3 and 11% for M = 2 are measured. Wavelength tuning of about 15 nm around the emission center has been realized by varying the intersection angle.
