Low-frequency beat noise for gas lasers
The beat frequency between modes of optical resonator with concave mirrors have been studied by the photomixing technique. In the experiment He-Ne laser(6328A)and Ar+ laser were used. Based on the random variation of cavity length, characteristics of the medium index and mode competition effect, low-frequency beat and noise continuums are explained.
