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

摘要

An optical lasing device (300) includes a gain medium (101) arranged in a lasing cavity having an optical axis, the gain medium (101) providing light amplification; a periodic grid generator filter (103) arranged in the lasing cavity; a channel selector (104) 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 (103) according to an optimization criterion; and a band-pass filter (305) arranged in the lasing cavity and configured to suppress lasing modes which are outside of a pass-band of the band-pass filter (305).
