Abstract
An all-solid-state single-frequency continuous wave laser is provided, which includes a symmetric ring resonant cavity, a first gain crystal and a second gain crystal symmetrically arranged in the symmetric ring resonant cavity, and a gain unit symmetrically arranged between the first gain crystal and the second gain crystal. The gain unit includes at least one gain crystal arranged in sequence. In the gain unit, a third gain crystal nearest to the first gain crystal and a fourth gain crystal nearest to the second gain crystal are symmetrically arranged. Each gain crystal is coupled with a separate pump source. Each gain crystal in the symmetric ring resonant cavity is equipped with a separate pump source, and the imaging system is eliminated in the symmetric ring resonant cavity. On the premise that the pump power is not limited, the laser can achieve stable single-frequency operation in a wide pump range.
