| 摘要 |
For laser sources comprising a regenerative amplifier or other single- or multi-pass amplifier setups a suitable substantially smooth laser diode pump spot is obtained from a laser diode array source or multiple arrays, by imaging each single emitter of the array or the arrays without focusing into substantially the same spot at the laser medium. <??>Due to the absence of focusing a comparatively low aspect ratio diode laser beam is achieved with a comparatively low intensity of the spot, which prevents thermal damages and other problems caused by higher intensities in the regenerative amplifier setup. <IMAGE>
