摘要： Laser systems have a line-narrowed master oscillator and a power oscillator for amplifying the output of the master oscillator. The power oscillator includes optical arrangements for limiting the bandwidth of radiation that can be amplified. The limited amplification bandwidth of the power oscillator is relatively broad compared to that of the output of the master oscillator, but narrower than would be the case without the bandwidth limiting arrangements. The bandwidth narrowing arrangements of the power oscillator function primarily to restrict the bandwidth of amplified spontaneous emission generated by the power oscillator.

摘要： An original laser-radiation beam having a symmetrical M2 but poor beam quality is sliced in one transverse axis, by a fanned-out stack of parallel transparent plates, into a plurality of beam slices. The beam-slices are also spread by the stack of plates in another transverse axis perpendicular to the first axis. A fanned-out stack of glass blocks aligns the spread beam-slices in the first axis to form what is effectively a single beam having an asymmetric M2, with beam quality improved in one axis and degraded in the other compared with the original beam. The effective single beam is projected into a line of radiation by a cylindrical lens, or by a homogenizing projector including spaced apart cylindrical lens arrays followed by a spherical condenser lens.
