Abstract

Optical homogeneity of organic dye-doped sol-gel silica slab has been improved. Single longitudinal mode laser oscillation with 1.58GHz linewidth at 467nm wavelength has been achieved. The first operation of a distributed feedback dye-doped sol-gel silica laser, with periodic gain modulation induced by the interference pattern of the pump laser beams, has been demonstrated in the red and the blue optical regions. 2Onm wavelength tuning range, 4.5%slope efficiency and 6Opm laser linewidth have also been obtained. Based on the quenching ofphosphorescence by oxygen, a novel oxygen sensor has been developed using erythrosin B doped sol-gel silica. The oxygen sensing is effective from O.Ol4mbar to 600mbar, and the sensitivity improves by a factor of 10 as compared to transition-metal optical fiber oxygen sensors.
