A technique called echelon-free induced spatial incoherence is proposed for producing
smooth, controllable target beam profiles with large KrF fusion lasers. The idea is basically …

We have achieved stable Fourier transform limited single axial mode operation of an
unstable resonator Nd: YAG oscillator by injection seeding of an external signal. A detailed …

Multistage, e-beam-pumped, 100 J-class KrF laser installation “GARPUN” is described with
the emphases to high-power laser beam control and target irradiation experiments. The …

On décrit diverses techniques pouvant être utilisées pour le rétrécissement spectral et la
syntonisation des oscillateurs à laser excimère. Les éléments dispersifs intra-cavité incluent …

We review the basic criteria for effective and efficient injection locking of high-power excimer
lasers, and enumerate the various parameters of practical concern for experimental …

We describe a high-performance Raman lidar system with combined day and night
capability for tropospheric water-vapor profile measurements. The system incorporates high …

Experimental observations on a double-pass methane Raman amplifier pumped by a KrF
laser demonstrate efficient photon extraction (75-85 percent) of multiple pump pulses and …

We are investigating the use of a low-divergence (100, μrad) KrF laser to trigger 2.8-MV gas
switches for lage pulsed-power systems. Using less than 0.1 J of laser energy, we have …

Intensity averaging of pump beams in a Raman amplifier can be treated using a four-wave
mixing model. The model shows explicitly the consequences of finite pump beam correlation …

KrF laser-triggered spark gaps exploit the high dc-dielectric strength and low ultraviolet (UV)
breakdown threshold of SF6 gas. Detailed measurements using a dc-charged pulser …
