We present measurements of the transverse and longitudinal coherence lengths of the fourth harmonic of a 1053-nm, 2.5-ps laser generated during high-intensity (up to ${10}^{19}$ W ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}2}$) interactions with a solid

Peak intensities of 1019 W cm2 have been reliably obtained from a high power Nd:glass laser using chirped pulse amplification. An Additive Pulse Modelocked oscillator incorporating diode pumped Nd:LMA was used to generate the sub-picosecond pulse. Th

Evidence of high gain pumped by recombination has been observed in the 5g-4f transition at 11.1 nm in sodiumlike copper ions with use of a 20-J 2-ps Nd:glass laser system. The time- and space-integrated gain coefficient was 8.8 +/- 1.4 cm(-1), indica

The interaction of an intense short pulse laser (>5/spl times/10/sup 18/ Wcm/sup -2/) with underdense plasma was extensively studied. The beam is found to be highly susceptible to the forward Raman scattering instability. At sufficiently high growth

The process of Chirped Pulse Amplification (CPA) as presently implemented on the VULCAN glass laser is capable of delivering 30 J to target with pulselengths in the sub- picosecond regime. Results from various experiments have shown that intensities
