Atomic vapor filter revisited: a Cabannes scattering temperature/wind lidar at 770 nm

Frequency Stabilization of a Diode Laser at 1540 nm by Locking to Sub-Doppler Lines of Potassium at 770 nm.

An external cavity 1540-nm diode laser was frequency doubled in a 3-cm-long periodically poled LiNbO(3) waveguide doubler with 150% W(-1) conversion efficiency, thereby generating more than 3 muW at 770 nm. Second-harmonic light was used to detect and lock to sub-Doppler lines of the (39)K D(1) transition.

ππ–scattering lengths at O(p6) revisited

This article completes a former work where part of the O(p6) low-energy constants entering in the ππ scattering were estimated. Some resonance contributions were missed in former calculations and appreciable differences appeared with respect to our outcome. Here, we provide the full results for all the contributing O(p6) couplings. We also perform a reanalysis of the hadronic inputs used for th...

Super Efficient Absorption Filter for Quantum Memory using Atomic Ensembles in a Vapor

We demonstrate how a natural rubidium vapor cell can efficiently filter out a pump beam that produces an Raman gain in the stimulated Raman process at the D2 line of Rb. We observe a Raman gain of at least 12 dB in Rb when the pump beam is detuned below the first transition in Rb, while being exactly on-resonance with the first transition in Rb. With a single pass through a second cell, we obse...

A heated vapor cell unit for dichroic atomic vapor laser lock in atomic rubidium.

The design and performance of a compact heated vapor cell unit for realizing a dichroic atomic vapor laser lock (DAVLL) for the D(2) transitions in atomic rubidium is described. A 5 cm long vapor cell is placed in a double-solenoid arrangement to produce the required magnetic field; the heat from the solenoid is used to increase the vapor pressure and correspondingly the DAVLL signal. We have c...
