Research on semiconductor laser frequency stabilization

Narrow linewidth and high stability of frequency are extremely necessary in modern precision experiments. The frequency of a free running semiconductor laser will drift several GHz per day, far too much to fulfill the demands in atomic and laser physics. In order to overcome this disadvantage, a variety of technologies for frequency stabilization are researched. The experimental realizations of frequency stabilization based on 780nm semiconductor laser are described in detail. Meanwhile, the performance and capabilities of the various frequency stabilization technologies are analyzed.
