Abstract

Lasing is observed near 620 nm in a DCM dye doped TiO2-content organically modified silicate (ORMOSIL) pumped by frequency-doubled radiation from a diode-pumped Q-switched Nd:YAG laser. The laser wavelength is tunable over 60 nm. A conversion efficiency of 18% is obtained at its central wavelength of 621 nm. The laser output energy has only a 10% reduction after 27,000 pulses at a pump repetition rate of 30 Hz and a pump intensity of 1 J/cm2. An all-solid-state, compact, long-lifetime, and tunable dye laser has been demonstrated.
