Then some improvements which bestow the cavity with certain characteristics are achieved on the basis of the original laser. There are more adjustment factors, such as the detuning of gratings and the length of the cavity. The resonance cavity can make use of each other better, and the synchronization of the dual-wavelength laser can be improved.
