Abstract:
An investigation was made of the energy parameters of a SF6–H2 radiation-chemical laser operating at pressures up to 10 atm. The active mixture was initiated by an electron beam formed in a field-emission coaxial diode. The maximum energy of the laser radiation obtained from a SF6:H2 = 70:1 mixture at a pressure of 2.7 atm was 0.79 J, which corresponded to a specific energy output of 21 mJ/cm3. The efficiency of conversion of the electron beam energy into laser radiation was 5%.
