The output characteristics of three-channel waveguide arrays CO2laser
The far-field output characteristics of throe-channel hollow bore ridge (HBR) waveguide arrays CO2 laser are investigated theoretically and experimentally. The far-field patterns of three different output modes are observed. Since there is a difference between the experimentally measured values and the theoretical values at normal hypothesis, the normal hypothesis conditions are revised in this paper, and the theoretical expression is derived. It is in agreement with experimental vesults.
