Study on the relation between laser noise and optical frequency transmission

摘要

By use of a linewidth measurement method based on the 120 degree difference interferometer, we study on the relation between laser noise and optical frequency transmission, such as the evolution of frequency noise and linewidth characteristics before and after transmission. Meanwhile, we chose some different typical commercial narrow-linewidth lasers: EMCORE, RIO, and NKT-X15 as optical carrier to demonstrate the effect of linewidth on transmission stability.
