Sub-Doppler spectroscopy of Rydberg atoms via velocity selection memory in a hot vapor cell
Esther Butery, Biplab Dutta, Stephany Santos +4
We study resonance redistribution mechanisms inside a hot vapor cell. This is achieved by pumping atoms on the first cesium resonance, 6S1/2-->6P1/2, and subsequently probing the v…
Coverage threshold for laser-induced lithography
Weliton S. Martins, Marcos Oriá, Thierry Passerat de Silans +1
Recent experimental observations of laser-induced adsorption at the interface between an alkali vapor and a dielectric surface have demonstrated the possibility of growing metallic…
Laser-induced atomic adsorption: a mechanism for nanofilm formation
Weliton S. Martins, Thierry Passerat de Silans, Marcos Oriá +1
We demonstrate and interpret a technique of laser-induced formation of thin metallic films using alkali atoms on the window of a dense-vapour cell. We show that this intriguing pho…
Selective reflection technique as a probe to monitor the growth of a metallic thin film on dielectric surfaces
Weliton Soares Martins, Marcos Oriá, Martine Chevrollier +1
Controlling thin film formation is technologically challenging. The knowledge of physical properties of the film and of the atoms in the surface vicinity can help improve control o…
Two-beam nonlinear Kerr effect to stabilize laser frequency with sub-Doppler resolution
Weliton Soares Martins, Hugo L. D. de S. Cavalcante, Thierry Passerat de Silans +2
Avoiding laser frequency drifts is a key issue in many atomic physics experiments. Several techniques have been developed to lock the laser frequency using sub-Doppler dispersive a…
Laser stabilization to an atomic transition using an optically generated dispersive lineshape
Fabiano Queiroga, Weliton Soares Martins, Valdeci Mestre +4
We report on a simple and robust technique to generate a dispersive signal which serves as an error signal to electronically stabilize a monomode cw laser emitting around an atomic…
