Keywords:optical bottle beam, second harmonic generation, hemispherical cavity

Optical bottle beams carry a 3D dark core, i.e. ‘zero intensity’ region, surrounded by bright region, and they have widely received much attention in a variety of fields, such as optical tweezers for atom trapping and particle guiding, optical imaging and fluorescence microscopes with high 3D spatial resolution.In this work, we report on the first demonstration of high-order bottle beam generation by employing intra-cavity second harmonic generation in a strongly pumped hemispherical Nd:YVO4 laser resonator.
