Effects of a prepulse in the femtosecond-pulse-driven Xe IX laser
Journal of the Optical Society of America B: Optical Physics 14:10 (1997) 2735-2741
Abstract:
We describe experiments that demonstrate the detrimental effect of a prepulse on the femtosecond-pulse-driven Xe IX laser. The mechanism of this effect is discussed in terms of the results of a hydrodynamic model of the preplasma formed by the prepulse. The benefit of inserting a simple electro-optic switch that allows full transmission of the main driving pulse, but reduces the prepulse to a level at which no preplasma is formed, is demonstrated experimentally. © 1997 Optical Society of America.Light at the end of the tunnel?

Abstract:
We present measurements of the net-induced gain on the 5d-4f transition at 186 nm in LiYF4:Nd3+ optically pumped by radiation from a molecular fluorine laser. It is found that for LiYF4: Nd3+ one of a series of potential continuously tunable VUV lasers, relatively strong excited-state absorption results in net-induced loss. The prospects for VUV laser operation being realised in other rare-earth-doped fluorides is discussed.Laser ablation of polymeric materials at 157 nm
