Abstract
Systems and techniques are disclosed for flat-top intensity laser sheet beam generation. The system includes a source of light directed at a first optical component arranged to receive the light and generate spherical aberration (e.g., third order positive aberration) in the light rays. The spherical aberration results in positive aberrations in the light in a first plane and also results in the light being substantially collimated in a second plane perpendicular to the first plane. In some cases, the source of light is provided from a laser diode and the first optical component is one of an aspherical lens and a spherical lens. The system also includes a second optical component for focusing the light in the second plane. In some cases, the second optical component is a cylindrical lens.
