Abstract
Nearly transform limited pulses of Lyman-α radiation at 1216 Å have been produced by sum frequency generation in 0.1 to 10 torr of mercury vapor. The input beams, consisting of photons at 3127 Å and 5454 Å, originate in 1 MHz bandwidth 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 6IS to 71S 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 Å and intense fluorescence from the 61P state at 1849 Å. A dramatic reduction of the 1849 Å radiation occurs when the 5454 Å beam is added to the cell. We have studied the intensity and linewidth dependance of the output radiation on input beam intensity, mercury density, and phase matching buffer gas pressure and composition.
