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 کاملAnalysis of photodecomposition of gaseous chlorobenzene by KrF excimer laser.
Gaseous monochlorobenzene was irradiated with KrF excimer laser (248 nm) under reduced pressure. The photodecomposition was an apparent first order reaction. When the system contained no additive gas, the photolysis was found to give benzene (conversion yield: 49%) in the gas phase and many unidentified products in the solid phase. On the other hand, in the presence of oxygen, carbon dioxide (1...
متن کاملFast - Discharge - Initiated KrF Laser
Intense laser emission has been observed from the KrF molecule formed by a chemical reaction initiated by fast-discharge circuitry. With a gas mixture of He:Kr:NF, = 500:50:1 and a sample pressure of 700 Torr, an output energy of 0. 8 mj was measured from a 25-nsec laser pulse (FWHM). Spectral analysis of the laser emission indicated laser action at 248.5 and 249.5 nm.
متن کاملCharacterisation of dentin surfaces processed with KrF excimer laser radiation.
In the present work, the surface microtexture and chemical changes induced in human dentin by laser processing with KrF excimer laser radiation using fluences ranging from 0.5 to 20 J/cm2 were studied by SEM, XPS and FTIR. Two distinct behaviours were observed in the evolution of surface topography. In some samples, the laser-treated surface remained flat, independently of the fluence used. It ...
