摘要：
Projection apparatus for projecting a radiation spot on a working plane includes a plurality of stacks of diode-laser bars. Each stack provides a beam of laser radiation. The diode-laser bars in each stack are arranged one above another in the fast-axis direction of the diode-laser bars. A corresponding plurality of beam-expanders expands the beam from the corresponding diode-laser bar stack in the slow-axis direction of the diode laser bars only. A focusing lens collects the slow-axis expanded beams and projects the slow-axis expanded beams into the working plane to form the radiation spot.
