摘要
A robust external cavity diode laser （ECDL） insensitive to mechanical vibration is built with an interference filter for selecting wavelength and a cat-eye reflector for light feedback. The free-running laser has a linewidth of 72 kHz. The laser frequency stability reaches 3×10^-12 at 1-s integration time in terms of relative Allan variance based on the saturation absorption spectrum.
