Implication

Experimental study demonstrates a 30 dB noise reduction in single-frequency fiber lasers via feedback, highlighting a method to stabilize outputs without environmental isolation.

Key Points

To evaluate the low-frequency noise properties of a single-frequency linear fiber laser and determine the effectiveness of feedback-based noise suppression without environmental isolation.
Characterized the low-frequency noise profile of a single-frequency linear fiber laser operated with and without active noise suppression feedback.
Conducted noise measurements in an open environment lacking mechanical or thermal isolation.
Without feedback, the peak root-mean-square relaxation oscillation at 182 kHz was 82.1 dB/Hz below the DC laser level.
With active feedback applied, the peak oscillation noise decreased to 112.1 dB/Hz below the DC level, achieving a 30.0 dB/Hz reduction.
