“…Yu Li in Northwest Institute of Nuclear Technology (China), has set up an optically pumped XeF(C-A) laser system working at 0.1-1 Hz pulse-repetition rate, and has obtained a maximum output energy up to 18.7 J and a conversion efficiency of 0.25% [6]. Recently, a new concept [7][8] of the direct amplification of femto-second optical pulses in photochemically driven XeF(C-A) active media is now being developed, by which the second harmonic of a Ti:Sapphire laser can be amplified.…”

This paper presents the results of studies on high power photochemical XeF(C-A) laser with repetition mode. A new design of optical pumping source is proposed and the deposition efficiency is higher than 75 %. The form process and the temporal and spatial characteristics of the XeF 2 photodissociation wave are studied experimentally. The results indicate that when the deposition power is 12.5 MW/cm, the maximum brightness temperature reaches more than 25 kK and the photon flux obtained more than 4×10 23 photon s -1 cm -2 in the VUV range of 130 nm~180 nm. A novel XeF(C-A) laser which can be operated in repetition mode has been developed based on surface discharge optical pumping technique. The ideal output energy results of 20 laser pulses are presented under different repetitive rates and their optimal experimental conditions. Output energies of more than 4J and better stability can be obtained when the laser device operates at 1, 2 and 5 Hz, respectively. When the gas feed rate is larger than 53L/s, the average energy of 20 laser pulses is up to 3.2J at the repetitive rate of 10Hz. The technology for the laser spectral narrowing is studied.

Evolution of spatial and energy characteristics start pulse with energy of 0.8 mJ in duration of 2 ps in the XeF(С-A) amplifier of THL-100 laser system have been studied experimentally and by numerical simulation. Laser radiation energy E = 2 J was obtained experimentally. In that work we present the 3D-model amplification of conically diverging laser beams, that takes into account the spatial inhomogeneity of the pump, and the geometry of THL-100 laser system amplifier. Description and the test results of the model are submitted. At the start pulse energy 0.8 mJ, the calculated radiation energy at the XeF(С-A) output reaches 2.4 J. Simulation results shows that, maximal intensity of the laser radiation in this mode reaches P = 60 GW/cm 2. The evolution of the energy and space-time structure of the laser beam in the amplifier was investigated. It is shown that in the ideal case (excluding the processes of nonlinear interaction of laser beam with an active medium), at the start pulse energy of 5 mJ, the energy of the laser radiation at the output of the amplifier is increased to E out = 3.8 J. In this mode, the maximal radiation intensity reaches a value of I = 148 GW/cm 2 .

With a comparatively simple design, a wavelength tunable optically pumped XeF(C–A) laser with narrow linewidth is set up. Experiments are performed under different conditions to narrow the linewidth of the XeF(C–A) laser to the range of 0.2–1 nm, with an output energy of higher than 2 J in the spectral range of 460–500 nm. The wavelength of the XeF(C–A) laser can be tuned in the spectral range of 448–518 nm.
