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. |

1. An optical lasing device comprising:
a gain medium arranged in a lasing cavity having an optical axis, wherein the gain medium provides 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, wherein the channel selsctor comprises a Guided Mode Resonance tunable mirror, and wherein the Guided Mode Resonance tunable mirror comprises at last one active layer having a tunable refractive index which is tunable between a first value and a second value higher than the first value. |
