| 英文摘要 | A plurality of diode lasers is focussed onto a single region by arranging the diodes at equally spaced locations on a first arc. Each diode laser emits light in a slit-like pattern which is characterized by orthogonal axes. In a first group of cylindrical lenses, one associated with each diode laser, each lens has a refractive surface having an axis parallel to one of the emitting axes of the laser and refracts light to a focal region of defined dimensions. Each cylindrical lens is disposed along a second arc having a circular center common with the first arc. A second group of cylindrical lenses, one associated with each laser, is also disposed on a circular arc, concentric with the other arcs, but the second group has a refractive axis perpendicular to the first refractive axis. The second group of cylindrical lenses acts upon the second axis of the source image, focussing it to the common focal region. The first and second cylindrical lens groups may be combined into a toric surface within a single lens. The cylindrical lenses may either be individual lenses, or may be combined into a lenticular array. The lenses may be simple cylindrical refractive lenses, Fresnel lenses, or holographic lenses. A bright image of the source is formed at the common focal region. The diode lasers and cylindrical lenses may be arranged in three dimensions to produce very high optical power densities. |
