title: Efficient tunable solid-state laser near 630 nm using sulforhodamine 640-doped silica gel.
abstract: Lasing is observed near 630 nm in a sulforhodamine 640-doped silica gel pumped by frequency-doubled radiation from a Q-switched Nd:YAG laser. A conversion efficiency of 20% is obtained. The laser wavelength is tunable over 40 nm.
