Laser 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 ...
متن کاملFemtosecond 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 کاملSurface Modification of TIMETAL 834 by Excimer Pulse Laser
Ti alloys become very popular in various engineering fields due to its light weight, high strength and good corrosion resistance properties. Nevertheless, its application is limited in many areas like: tribology, high temperature oxidation and aggressive corrosion fields due to its poor surface properties. Therefore, the proper surface treatment is required to increase the usageof Ti alloys in ...
متن کاملA Long Pulse Discharge Excited ArF Laser
An X-ray preionised, discharge excited ArF excimer laser, = 193 nm, has been studied in the long pulse regime. The laser performance is found to be primarily dependent on the discharge stability, and therefore, on the gas composition, preionization timing and the pumping power. Using X-ray preionization and prepulse-mainpulse excitation, laser pulselengths of up to 120-ns full-width at half-max...
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...
