Nearly transform limited pulses of 1216 A radiation have been generated by sum frequency generation in 0.1 to 10 torr of mercury vapor. The summed input beams, consisting of photons at 3127 A and 5454 A originate in 1 MHz band-width ring-dye laser oscillators. The beams are amplified in pulsed-dye amplifiers pumped by the frequency doubled output of a Nd:YAG laser. The 3127 A photons are tuned to be resonant with the two-photon 6{sup 1}S to 7{sup 1}S mercury transition. The VUV radiation can be tuned by varying the frequency of the third non-resonant photon. We have also observed difference frequency generation at 2193 A and intense fluorescence from the 6{sup 1}P state at 1849 A. We have studied the intensity and linewidth dependence of the 1849 A fluorescence and 1216 A sum frequency signals on input beam intensity, mercury density, and buffer gas pressure and composition.
