Improvement of the intensity noise and frequency stabilization of Nd:YAP laser with an ultra-low expansion Fabry-Perot cavity

Juan Yu, Yue Qin, Zhihui Yan +2 more

Continuous-wave, single-frequency, solid-state lasers with long-term frequency stability and low-intensity noise are an essential resource to generate squeezed and entangled states of light. In order to obtain the stable, nonclassical states of light, the frequency of the laser has to be stabilized with a stable reference. Due to the zero expansion property at a certain temperature, an ultra-low expansion (ULE) Fabry-Perot (F-P) cavity with a high finesse can be used as one of the best candidates of the frequency reference. We perform a detailed analysis of an extraordinarily high-frequency stability and ultra-low-intensity noise laser based on an improved cascade Pound-Drever-Hall frequency stabilization to a ULE F-P cavity. The frequency drift of the laser is suppressed to 7.72 MHz in 4 hours, and the noise level of the laser is simultaneously reduced to the quantum noise limit in the frequency below 300 kHz, which provides the possibility for the direct generation of a stable, high-level squeezed state in a lower-frequency region.

Subluminal Optical Temporal Solitons in Asymmetric Three Coupled Quantum Wells

S. Shwetanshumala, Swapan Konar

We have explored the possibility of generation and propagation of ultraslow bright optical temporal solitons in asymmetric three-coupled quantum well systems. These bright solitons owe their existence to Kerr and quintic nonlinearities which arise due to a probe pulse and two controlling laser beams. We also find numerically that these solitons are stable against weak perturbation. General Terms Subluminal, Temporal solitons, Coupled quantum wells.

Phase Noise Characterization of an Ultra-Stable Industrial Clock Laser System via Cross-Correlation Analysis

Dewni Pathegama, Florian Schäfer, Filippo Bregolin

As more and more quantum applications are brought outside of laboratories, the demand for compact, robust laser systems with high frequency stability are increasing [1]–[3]. For many such applications, achieving fractional frequency stability below$2\times 10^{-15}$for averaging times between 0.1 and 100 seconds is critical. Here we present the characterization of a TOPTICA Photonics Clock Laser System (CLS), a transportable, rack-mounted ultra-stable laser system, and discuss its suitability for quantum applications. Further, we quantify the system performance with respect to the impact of environmental conditions such as seismic and acoustic vibrations, fiber induced phase noise and optical power fluctuations. We characterize our system over an offset frequency range from 1 mHz up to 10 MHz. We show that our system reaches a fractional frequency stability of$4\times 10^{-16}$at 1 s averaging time.
