A reliable laser system, capable of generating 10 mW average power of tunable narrowband deep UV radiation around 210 nm is demonstrated. The system is based on a 6.5 kHz repetition rate copper vapour laser pumped dye laser. The dye laser emission is subsequently tripled by phasematched second harmonic generation and sum-frequency mixing in two BBO crystals. An application of the present system for high resolution excitation around 213 nm of the 1B 2( 1Σ +u) state of the CS 2 molecule and a resultant total fluorescence spectrum is given as an example.
