rubidium vapour mixing

Rubidium cannot be stored under atmospheric oxygen as a highly exothermic reaction will ensue sometimes even resulting in the metal catching fire Rubidium is the first alkali metal in the group to have a density higher than water so it sinks unlike the metals above it in the group Abstract We demonstrate efficient four-wave mixing with an intensity conversion efficiency of nearly in theory without considering the Doppler-broadening effect in a four-level double-Λ system of hot 87 Rb gas The corresponding experimental value of about 73% was reported in our earlier work under the same conditions

Abstract: Laguerre-Gauss beams and more generally the orbital angular momentum of light (OAM) provide valuable research tools for optical manipulation processing imaging and communication Here we explore the high-efficiency frequency conversion of OAM in a four-wave mixing process in rubidium vapour Conservation of the OAM in the two pump beams

Four-wave-mixing stopped light in hot atomic rubidium vapour By Ryan M Camacho Praveen K Vudyasetu and John C Howell Abstract Digital signal processing holography and quantum and classical information processing rely heavily upon recording the amplitude and phase of coherent optical signals

Potassium vapour magnetometer Potassium is the only optically pumped magnetometer that operates on a single narrow electron spin resonance (ESR) line in contrast to other alkali vapour magnetometers that use irregular composite and wide spectral lines and helium with the inherently wide spectral line Applications

A similar effect was observed with a rubidium atomic vapor cell but to more definitively investigate this system we first need to accurately characterize that vapor cell in particular by finding the exact cell thickness In this paper I discuss fifth the fourwave mixing

Relevant Rb energy levels for the four-wave mixing process (Top) 1mW of 420nm light from ~20+20mW of focused 780nm and 776nm light (Bottom) 420nm beam power with (blue 1MHz linewidth) and without (red) a ring cavity Experimental image of a 420nm laser beam carrying trans-spectral OAM transferred from the near-infrared pump beams

We report the first use of a ring cavity to both enhance the output power and dramatically narrow the linewidth (1 MHz) of blue light generated by four-wave mixing in a rubidium vapor cell We find that the high output power available in our cavity-free system leads to power broadening of the generated blue light linewidth
