Trapping and transporting aerosols with a single optical bottle beam generated by moiré techniques

We demonstrate optical trapping and manipulation of aerosols with an optical bottle beam generated by the moiré techniques. We observe stable trapping and back-and-forth transportation of a variety of absorbing carbon particles suspended in air, ranging from clusters of nanosized buckminsterfullerene C₆₀ to micrometer-sized carbon powders.
