Femtosecond gain characteristics of the discharge-pumped ArF excimer amplifier.
The gain characteristics of a discharge-pumped ArF excimer amplifier are measured with ~700-fs-long pulses. The small-signal gain and saturation energy are found to be 0.17 cm(-1) and 3.65 +/- 0.15 mJ/cm(2), respectively. The maximum output energy density extracted from the deeply saturated amplifier is as much as 10 mJ/cm(2). The demonstrated femtosecond gain characteristics of ArF indicate th...
متن کاملGas - discharge XeF * laser with high specific output energy
The discharge characteristics of the XeF* (B~X) laser are investigated. The NF3 and Xe partial pressure of the laser gas mixture and the total gas pressure have been varied. A highest specific output energy of 4.7 J/1 with an efficiency of 0.5% was obtained from a X-ray preionized Ne/Xe/NF3 gas mixture at 6 bar with single-pulse excitation through a multichannel spark gap. PACS: 42.55.Gp, 42.60...
متن کاملOptimisation of the pulse duration of a discharge-pumped XeF( <Emphasis Type="Italic">BX </Emphasis>) excimer laser
In an x-ray preionised XeF(B~X) dischargeexcited laser driven by a magnetic-spiker sustainer circuit with a magnetic pulse compressor the influence of the various parameters on the optical pulse duration was experimentally investigated. Laser pulses at 2= 351 nm with a duration of 212 ns (FWHM) have been achieved in a NF3/Xe/Ne mixture by using very low (0.25 mbar) NF3 partial pressures in a to...
متن کاملOptically pumped microplasma rare gas laser.
The optically pumped rare-gas metastable laser is a chemically inert analogue to three-state optically pumped alkali laser systems. The concept requires efficient generation of electronically excited metastable atoms in a continuous-wave (CW) electric discharge in flowing gas mixtures near atmospheric pressure. We have observed CW optical gain and laser oscillation at 912.3 nm using a linear mi...
متن کاملLaser gain measurements at 193 nm in a small discharge cell containing ArF excimer laser gas mixtures
Spatial and temporal gain profiles as well as the peak net gain at 193 nm have been measured in X-ray preionized discharges excited by a single pulse electrical system working in the charge transfer mode. Arand F2-containing laser gas mixtures with He or Ne as a buffer gas have been used. With a pumping pulse duration of ∼ 100 ns (FWHM) and a specific peak power deposition of ∼ 1 MW cm−3 bar−1 ...
