Paper Abstract

The most interesting features in the fields of laser engineering and laser physics are efficient generation of new wavelengths, compact size of devices, analysis of unknown kinetics, feasibility of various applications, high power, and high efficiency etc. In view of these terms XeF* excimer has many attractive points. Recently, the blue-green XeF(C->A) laser has been investigated in various operational modes to obtain high-energy and high-efficiency under the high excitation rate with high pressure[1] and low excitation rate with intermediate pressure of laser gas[2]. Furthermore operational characteristics of atmospheric-pressure are newly focused[3-5]. The use of laser medium with low pressure (≤1 atm) is proposed for solving nonlinear problems in ultrashort pulse amplifier[5]. Also that condition offers several advantages such as the use of thin optical windows, easy handling, and low cost. This paper describes the increased intrinsic efficiency as a functions of Xe concentration for the condition of atmospheric-pressure XeF(C->A) excimer laser with electron-beam (e-beam) excitation.
