Subhertz linewidth laser by locking to a fiber delay line

Abstract

An ultralow-noise, subhertz 1.55 μm erbium-doped fiber laser that is locked on an all-fiber-based Michelson interferometer is presented in this paper. The interferometer uses 500 m SMF-28 optical fiber and an acousto-optic modulator to allow heterodyne detection. By comparing two identical laser systems, a 0.67 (0.21) Hz linewidth beat-note signal is achieved and we obtain fractional frequency instability of 7×1015 at short timescales (0.1–1 s). The frequency noise power spectral density of two identical lasers is below 1dBHz2/Hz at 1 Hz and it reaches 18dBHz2/Hz from 200 Hz to 1 kHz.
