This paper reports on CuBr-AgBr-Ne lasers operating at 35 kHz of repetition frequency, 15 kV of charging voltage, 0.56 nF of discharge peaking capacitor, and 1920 W of input power generated 13.5 W of average output power with a homemade simple laser tube 45 cm long and 2.6 cm (inner diameter) i.d. The power efficiency was, therefore, about 0.7%. The maximum repetition frequency was reached at 40 kHz. These results were qualitatively but reasonably interpreted by introducing two assumptions. First, the upper laser level enhancement by collisional energy transfer from a response of Ag atoms to a resonance state of Cu atoms and second, the effective relaxation of lower laser levels by plasma - chemistry recombination process of the Cu atoms in a metastable state with the Br{sup {minus}} ions. By taking into account the melting point as well as the dissociation energy of the chemicals, the reasons for these experimental results was also explained.
