Gouy phase-matched angular and radial mode conversion in four-wave mixing
Rachel F. Offer, Andrew Daffurn, Erling Riis +3
Studying the conversion between transverse light modes via four-wave mixing in a heated rubidium vapour, we demonstrate and explain a transfer between azimuthal and radial mode num…
Tight focal spots using azimuthally polarised light from a Fresnel cone
R. D. Hawley, R. Offer, N. Radwell +1
When focusing a light beam at high numerical aperture, the resulting electric field profile in the focal plane depends on the transverse polarisation profile, as interference betwe…
Spiral bandwidth of four-wave mixing in Rb vapour
Rachel F. Offer, Dalius Stulga, Erling Riis +2
Laguerre-Gauss beams, and more generally the orbital angular momentum of light (OAM) provide valuable research tools for optical manipulation, processing, imaging and communication…
Cavity-enhanced frequency up-conversion in rubidium vapour
Rachel F. Offer, Johnathan W. C. Conway, Erling Riis +2
We report the first use of a ring cavity to both enhance the output power and dramatically narrow the linewidth (MHz) of blue light generated by four wave mixing in a rubidiu…
