Optical lasing device and method for generating a lasing mode in such device

摘要

An optical lasing device includes a gain medium arranged in a lasing cavity having an optical axis, the gain medium providing light amplification; a periodic grid generator filter arranged in the lasing cavity; a channel selector arranged in the lasing cavity and configured to select a lasing mode of the amplified light corresponding to a frequency channel defined by the periodic grid generator filter according to an optimization criterion; and a band-pass filter arranged in the lasing cavity and configured to suppress lasing modes which are outside of a pass-band of the band-pass filter.
