Abstract

Design, sealed-off operation and optical properties of a 12 kW transverse flow C02-laser with rf-excitation are discussed. The design is characterized by transverse gas flow, rf-excitation, an unstable double pass resonator and an integrated catalyst. The sealed-off-operation is investigated by measuring the CO- and NO-concentrations and the small signal gain as functions of the operating time. The optical properties, determined by the compensation of the density gradient in flow direction which is inherent to transverse flow lasers, are investigated in several experiments.
