Partially coherent bottle beams

The Structure of Partially Coherent Fields

“…For instance, it has been suggested by Gbur and Visser (2003a), Pu et al (2004), and van Dijk et al (2008) that the ability to shape the intensity in the focal region by spatial coherence could be used to develop novel optical trapping and optical manipulation schemes. In particular, Arlt and Padgett (2000) introduced the term "bottle beam" to characterize a focused coherent field with an intensity minimum at the geometric focus; this term has also been adopted for describing partially coherent beams of this type by Pu, Liu, and Nemoto (2005).…”

Generation of multiple focal spot and focal hole segments using phase modulated cylindrically polarized annular multi-Gaussian beam

“…Growing interest in the generation of three-dimensional (3D) optical beams that are dark regions in space surrounded by light are driven by wide ranging applications including dark optical traps for atoms (Zhan and Leger 2002;Friedman et al 2002), manipulation, guiding and binding of microparticles and biological cells (Cizmar et al 2010), erase beams for super-resolution fluorescence microscopy (Watanabe et al 2003), etc. Over the past years, a variety of techniques have been proposed for generating such optical bottle beams for applications in optical tweezers and atom traps (GarciaSucerquia et al 2004;Chen and Zhan 2006;Bokor and Davidson 2006;Ahluwalia et al 2006;Arlt and Padgett 2000;Ahluwalia et al 2004;Yelin et al 2004;Pu et al 2005). However, stable trapping of a single particle is expected if we can make the bottles small enough and comparable to the particle size.…”

Generation of multiple focal holes by tightly focused azimuthally polarized double-ring-shaped beam with complex phase mask

“…Generation and application of optical bottle beams are one of the very interesting subjects in optics. It has attracted a great deal of attention and has been developed fast in recent years [2][3][4][5][6][7][8]. Over the past several years, a variety of techniques have been proposed for generating such optical bottle beams for applications in optical tweezers and atom traps [9,10].…”
