OPTICAL CAVITY RING POWER LASER SOURCE WITH HIGH SPECTRAL FINESSE

摘要

The invention relates to an optical cavity ring laser source, characterized in that said cavity comprises a pump gain fiber optic with a first end whose optical axis is optically aligned with an output mirror and a second end which is directed toward the first, the optical axis thereof intersecting the optical axis of the first end on the front surface of the first end and being distinct from the optical axis of the first end, also comprising a beam rephasing device and a non-reciprocal element respectively disposed between the second and first ends of the fiber optic.
