چکیده

We demonstrate the dual-frequency emission of a diode-pumped vertical external-cavity semiconductor laser operating at 852 nm, dedicated to the coherent population trapping of cesium atoms for compact atomic frequency references. It is based on a single laser cavity sustaining the oscillation of two adjacent, cross-polarized, modes. The output power reaches 10 mW on each frequency. The frequency difference and the absolute laser frequencies are simultaneously precisely tuned and stabilized on external references, resulting in the generation of a high-purity optically-carried microwave signal. The laser design has focused on stability and compactness.

Spectral and noise characterization of a 852 nm dual-frequency VECSEL

Coherent population trapping (CPT) is a common technique used in compact atomic clocks which requires two-phase coherent laser modes with a frequency difference in the GHz range for alkali atoms [1]. To improve the performance vs size trade-off of Cs atomic clocks, we develop a laser source generating two crosspolarized coherent laser fields at 852 nm. It relies on the dual-frequency and dual-p...

Implementation of a widely tunable microwave signal generator based on dual-polarization fiber grating laser.

In this paper, we demonstrate the implementation of a widely tunable microwave signal generator based on a dual-polarization fiber grating laser. The laser contains two strong, wavelength-matched Bragg gratings photoinscribed in an Er-doped fiber and emits two polarization modes when pumped with a 980 nm laser diode. By beating the two modes, a microwave signal with a signal-to-noise ratio over...

Wideband and frequency-tunable microwave generation using an optoelectronic oscillator incorporating a Fabry-Perot laser diode with external optical injection.

Wideband and frequency-tunable microwave signal generation using an optoelectronic oscillator incorporating a Fabry-Perot laser diode (FP-LD) with external optical injection is proposed and demonstrated. Through external injection, the FP-LD functions as a tunable high-Q photonic microwave filter, and the frequency tuning is realized by either tuning the wavelength of the externally injected op...

Simultaneous Dual-wavelength Generation from Vertical External-cavity Surface-emitting Semiconductor Lasers

We demonstrate dual-wavelength emission from optically pumped vertical-external-cavity surface-emitting lasers (VECSELs) with two different gain mirror designs. The first gain mirror design (S1) generated an optical output power of 0.39 W at λS = 984 nm and 0.30 W at λL = 1042 nm. A VECSEL using the second gain mirror design (S2) generated a maximum optical output power of 0.75 W at λS = 966 nm...

Transverse load sensing based on a dual-frequency optoelectronic oscillator.

We propose and experimentally demonstrate a fiber-optic sensor implemented based on a dual-frequency optoelectronic oscillator (OEO) for transverse load sensing. In the OEO loop, a phase-shifted fiber Bragg grating (PS-FBG) is employed to which a transverse load is applied to introduce a birefringence to create two orthogonally polarized notches, which leads to the generation of two oscillating...
