Abstract
A diode laser system having a diode amplifier member with a large transverse gain area. The diode amplifier member includes an amplifying medium for amplifying a number of spatial modes of a spatial light distribution. The laser system further includes a number of passive reflective members forming a laser cavity which includes at least a part of the diode amplifier member, each of the passive reflective members being adapted, during operation, to reflect light at least partially into the amplifying medium. The passive reflective members are adapted, during operation, to induce, via the light reflected by them, a self-induced dynamic gain and refractive index grating in the diode amplifier member, the dynamic gain and refractive index grating selecting one of said spatial modes and suppressing at least a part of the remaining spatial modes of the spatial light distribution.
