摘要： Disclosed is a diode laser system comprising 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 comprises number of passive reflective members forming a laser cavity which includes at least a part of the diode amplifier member, ecah 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.

摘要： An optical laser system wherein a holographic optical element (HOE) replaces a bulky feedback system comprising a large number of optical element. The feedback system is adjusted so that the laser device and the feedback system cooperate to select a state having a high temporal and/or spatial coherence, and the optical properties of the optical elements are recorded into the HOE. When the feedback system is removed the HOE reproduces the properties of the optical elements of the feedback system. The laser system is compact in size, cheap to manufacture, has high mechanical stability, and is less fragile than ordinary feedback systems. The laser system may be used in environments, such as the printing industry, which normally do not permit an ordinary feedback system, e.g. due to mechanical vibrations or misalignment due to temperature variations. A number of centre frequencies may be multiplexed into the HOE. May be mass produced. Furthermore, a method of producing such an optical laser system.
