Earlier studies have shown that the small signal gain of a CW HF chemical laser is rather high and the cavity pressure is low, hence mode competition and anomalous dispersion dominate the output modes of a resonator. The paper reports an investigation of the competition of longitudinal and transverse modes in stable and unstable resonators of a CW HF chemical laser. Strong mode competition and asymmetries of the modes are observed, but single longitudinal mode operation in a gain width of 250 MHz and mode spacing of 75 MHz is also observed.
