Frequency stability plays a crucial role for laser metrological applications. This paper first reviews the laser as a measurement tool in metrology. The techniques of laser frequency stabilization for metrological applications are then discussed from physical and engineering points of view. Finally, an example of recent advance in laser frequency stabilization is presented.
