Competition of longitudinal and transverse modes in a cw HF chemical laser
Abstract
Longitudinal and transverse mode competition in stable and unstable resonators of a single υ J-transition cw HF chemical laser were investigated. Single longitudinal mode operation in a long (> 2 m) resonator was achieved without decreasing laser output power. Asymmetric mode spectra were observed. These observations indicate that there is strong mode competition and a frequency-dependent loss mechanism caused by a limiting aperture and the effect of saturation of anomalous dispersion.
