Abstract

A laser with tunable outer cavity and a method for using same, said laser with tunable outer cavity comprising a gain chip (100), a collimating mirror (200), a wavelength selection element (300), and an optical path for the generation of an optical path difference (400). A cavity surface (1002) of the gain chip is located in a focal plane of the collimating mirror. The wavelength selection element is located between the collimating mirror and the optical path for the generation of an optical path difference. Light beams emitted from the cavity surface of the gain chip are collimated by the collimating mirror to form parallel beams which are sent to the wavelength selection element; the wavelength selection element filters the parallel beams from the collimating mirror and then sends them to the optical path for the generation of an optical path difference. The optical path for the generation of an optical path difference splits the parallel beams entering same into at least two branch beams, and reflects each of said branch beams to the gain chip according to the incident direction. The optical path for the generation of an optical path difference is able to adjust the optical path difference between the optical paths of the branch beams. Since the optical path for the generation of an optical path difference serves to roughly select a mode, there is no need for precise control of adjustment and the process of wavelength tuning and selection is made easier.
