Abstract
A polychromatic or white light laser arrangement for changing the dimensions of the pumped portions of the active medium is realized by employing an optical divider for dividing the pump radiation into at least two beamlets, and one or more lenses for focusing the pump radiation onto the active medium. In one preferred embodiment, the optical divider includes a system of mirrors and lenses, or an acousto-optic deflector.
