Lasers are widely used in precision spectroscopy and precision measurement. The laser frequency stability and spectral purity determine the measurement accuracy and precision. Therefore, lasers with even higher frequency stability and narrower linewidth are pursued. In this paper, we review the techniques of sub-hertz-linewidth lasers and prospect the ways to realize lasers even higher frequency stability.
