Locking noise in laser frequency stabilization to an optical fiber delay line
Abstract:
We investigate the noise due to the locking process in frequency stabilization of a laser onto an optical fiber delay line with the Pound-Drever-Hall method. Preliminary measurements revealed a white frequency noise floor that limited the locking performance. We conducted a combined experimental and theoretical analysis to identify the source of this limitation, focusing on the role of frequency discriminator nonlinearity. By increasing the locking bandwidth, we demonstrate a reduction in this white noise to a level where this nonlinearity is no longer a limiting factor.
