Laser diode apparatus, laser arrangement having at least one laser diode apparatus, and optically pumped laser

摘要

A laser diode apparatus ( 2 ) having a plurality of active regions ( 4 a . . . 4 n) which are arranged side by side and are designed for radiation production when the laser diode apparatus is in operation. A lateral dimension (b_a . . . b_n) of the active regions is varied in the lateral direction, and/or the distance (D_a . . . D₁) between adjacent active regions is varied in the lateral direction. Furthermore, a laser arrangement ( 1 ) is specified, having a laser diode apparatus which is arranged on a mount ( 6 ) with the mount being matched to the laser diode apparatus. Furthermore, a laser which is optically pumped by means of the laser diode apparatus or the laser arrangement is specified.
