Abstract: The development of a computer controlled tunable ultraviolet spectrometer utilizing intracavity second harmonic generation in a single frequency CW dye ring laser is reported. With 5 W of argon ion laser pump power at 514.5 nm, the spectrometer can generate typical single mode and multimode UV output powers of 20mW (linewidth ± 40 MHz) and 40 mW (linewidth ~ 80 GHz) respectively at the peak of the Rh6G laser power spectrum. Wavelength tuning extends from 287 to 305 nm utilizing the organic dye Rh6G and employing temperature phase matching of the nonlinear optical crystal ADA. The performance characteristics of the laser spectrometer have been evaluated by studying the absorption and fluorescence spectra of SO<sub>2</sub> around 295 nm. Detailed Doppler limited continuous single frequency UV scans of up to 1600 GHz have been routinely achieved.
