Phase Noise Quenching in a Four-Level Laser

Chinese Physics Letters, 2010
In the presence of usual transmission losses, it is shown that phase noise in a four-level laser can be reduced below the Schawlow–Townes limit when lasing levels are coupled to a squeezed vacuum reservoir. The squeezed vacuum coupled to the lasing mode modifies the phase diffusion rate and dominates the contribution from transmission losses.

Intracavity Phase Modulation for Phase Noise and Supermode Noise Spur Suppression in Mode-locked Lasers

Conference on Lasers and Electro-Optics/International Quantum Electronics Conference, 2009
Using intracavity active phase modulation, we have verified the theory of Haus and Rana and realized timing jitter reduction from 304 fs to 150 fs integrated to Nyquist frequency on a 10.24 GHz actively mode-locked pulse train.

Suppression of clock-jitter noise and laser phase noise in arm locking

Classical and Quantum Gravity
Abstract Arm-locking technique has been a focus of attention as one of the means to suppress the laser phase noise in space-based gravitational wave detector. The main idea of the arm-locking technique is to transfer the stability of the detector arm length to laser frequency by introducing a feedback control loop. Generally, laser phase

Conversion of laser phase noise to amplitude noise in an optically thick vapor

Journal of the Optical Society of America B, 1998
As laser light propagates through a resonant vapor, laser phase noise (PM) is converted to laser intensity noise (AM) because of the sensitivity of atomic coherence to laser phase fluctuations. In experiments reported here it is shown that this PM-to-AM conversion process is highly efficient and can cause the relative intensity noise of transmitted ...
