Abstract
The amplified spontaneous emissim (ASE) characteristics of the Kr F laser excited by an axially injected electron-beam have been studied with the fixed mixing gas ratio of Kr: F2: He=8: 0.2: 91.80 and the total gas pressure of 1-4 atm. The maximum efficiency (the conversion ratio from the pumping energy to the ASE energy) of 1.7% was obtained for the total gas pressure of 4 atm and the average pumping power density of 6.2 MW/cm3. Maximum ASE energy of 7.4 J was obtained.
