Abstract

characterized by two parameters, 0(T) and (T), allows the temperature-dependence of the cavity response, S0(T) and dS0=dT to be predicted over a range of temperature. We compare the predictions to experiment. Our model will be useful in determining the useful range for S0, given the practical constraints on temperature stability for an atomic vapor cell.

Temperature Sensitivity of an Atomic Vapor Cell-Based Dispersion-Enhanced Optical Cavity

Enhancement of the response of an optical cavity to a change in optical path length, through the use of an intracavity fast-light medium, has previously been demonstrated experimentally and described theoretically for an atomic vapor cell as the intracavity resonant absorber. This phenomenon may be used to enhance both the scale factor and sensitivity of an optical cavity mode to the change in path length, e.g. in gyroscopic applications. We study the temperature sensitivity of the on-resonant scale factor enhancement, S(sub o), due to the thermal sensitivity of the lower-level atom density in an atomic vapor cell, specifically for the case of the Rb-87 D(sub 2) transition. A semi-empirical model of the temperature-dependence of the absorption profile, characterized by two parameters, a(sub o)(T) and gamma(sub a)(T) allows the temperature-dependence of the cavity response, S(sub o)(T) and dS(sub o)/dT to be predicted over a range of temperature. We compare the predictions to experiment. Our model will be useful in determining the useful range for S(sub o), given the practical constraints on temperature stability for an atomic vapor cell.

Temperature sensitivity of the cavity scale factor enhancement for a Gaussian absorption resonance

Krishna Myneni, David D. Smith, Hongrok Chang +1 more

We derive analytic expressions for the on-resonant cavity scale factor enhancement dependence on temperature, ${S}_{0}(T)$, for an intracavity medium with a Gaussian absorption resonance. Results are expressed as functions of the cavity parameters and the two resonance parameters: ${\ensuremath{\alpha}}_{0}(T)$, the peak absorption coefficient, and ${\mathrm{\ensuremath{\Gamma}}}_{\ensuremath{\alpha}}^{R}(T)$, the resonance width. A semiempirical model is developed for the temperature-dependent absorption coefficient, ${\ensuremath{\alpha}}_{F}(\mathrm{\ensuremath{\Delta}},T)$, in an alkali-metal-atom vapor cell, and is used to compare the predicted behavior of ${\ensuremath{\alpha}}_{0}(T)$ and ${\mathrm{\ensuremath{\Gamma}}}_{\ensuremath{\alpha}}^{R}(T)$ with the measured values for the $D{}_{2}\phantom{\rule{0.28em}{0ex}}F=2\ensuremath{\rightarrow}{F}^{\ensuremath{'}}$ resonance in $^{87}\mathrm{Rb}$, over the temperature range 298--325 K. Measurements of ${S}_{0}(T)$ in a low-finesse ring cavity, using the same vapor cell as the intracavity dispersive medium, were performed and found to be in agreement with the temperature-dependent behavior predicted by our theory, with quantitative agreement to 2 K for the critical temperature. The practical range of ${S}_{0}$ is found to be limited by the achievable temperature stability of the resonance parameters of the dispersive medium.

Atomic-vapor laser interaction

Priscila Mayana Torres Barboza

In this work we investigate the transmission in an optical cell containing an atomic vapor, when a laser is tuned to the wings of the Doppler line, presenting inhomogeneous broadening. The experiment is designed to detect the transmission of a laser beam through a an atomic cesium vapor within a quartz cell. Due to the high atomic density in the 1 mm cell, the laser beam is totally absorbed at resonance. On the other hand, when the detuning by few GHz from the center of the line an oscillatory signal is observed as a function of the laser frequency. The amplitude of the transmission signal varies linearly with the laser intensity. These oscillations exhibit diferent behavior as we change some parameters of the system, and the rate of the oscillations vary with laser detuning and on the atomic density. The phase of the transmited field is also sensitive to the angle of incidence of the laser beam in the cell, which allows to vary the lineshape of the signal without changing the parameters of the laser (intensity, frequency, ...) or atomic vapor. Out of resonance with the atomic vapor, the parallel windows of commercial optical cell cavity works as a low finesse Fabry-Pérot with a free spectral range of 150 GHz. However, in resonance, the optical path of the cavity changes varies with frequency due to the dispersive response of the atomic vapor. This study experimentally characterized the transmission signal through a cavity containing resonant vapor as a function of intensity and frequency of the laser, as well as its dependence on the angle of incidence of the beam. A numerical model that allows to determine the collisional broadening of the atomic vapor adjusting the spectral curves of the transmission signal was developed. As an application, exploring the oscillations in the wings of the resonance, we can lock the laser frequency at a few GHz off the center of the atomic resonance. The lock was performed in the frequency range between 0,8 GHz and 2,4 GHz from the center of the D2 line of cesium. To characterize the locking stability we measure the optical beat signal between two similar experiments, using the same locking technique.
