摘要：
The present invention provides a wavelength monitoring and/or controlling device, preferably a wavelength locker, for monitoring and/or controlling the wavelength respectively frequency of an original laser beam received from a tunable laser, the device comprising a first beam splitter configured to divide the original laser beam into two beams with a predetermined angular displacement, and configured to differently polarize the two beams, such that a first beam of the two beams has a first polarization and a second beam of the two beams has a second polarization; and an etalon filter configured to filter the two polarized beams with the predetermined angular displacement. The present invention further provides a laser system comprising at least one such wavelength monitoring and/or controlling device according to the present invention and a method for operating such wavelength monitoring and/or controlling device according to the present invention.
