Keywords:Bottle beam generation, Raman laser

In this work, we present, for the first time to the best of our knowledge, the direct generation of a watt-level bottle beam from a self-Raman Nd:GdVO4 laser by employing a tight needle pumping beam with a long confocal length formed of two plano-convex lenses with spherical aberration.
