Paper Abstract

The characteristics and potential applications of high power pulsed electron beam controlled discharge (EBCD) N2O laser are discussed. The influence of pressure, temperature, composition, and components' ratio of laser mixture on the discharge properties, laser gain, and lasing parameters have been studied experimentally. The small signal gain measurements and N2O laser wavelength tuning were carried out for P- and R- branches of N2O molecule from P(2) to P(46) and from R(47) to R(2), respectively. The maximum specific output energies were 40 J/l atm (efficiency approximately 10%, free running laser mode), 16 J/l atm (P-branch line P(18), single line selective laser mode), and 12 J/l atm (R-branch line R(20), single line selective laser mode). The relaxation constant of N2O laser levels and the excitation efficiency in EBCD are estimated.
