The illumination optical system includes a beam shaper which converts an intensity distribution of a laser beam in each of a short axis direction and a long axis direction, which is a Gaussian distribution, into an intensity distribution of a parallel beam on a modulation surface of the optical modulator in each of the short axis direction and the long axis direction, which is a top hat distribution. The modulation surface and an irradiated surface are optically conjugated with respect to the long axis direction by a third lens and a fourth lens. Further, the modulation surface and a front focus position of the fourth lens are optically conjugated with respect to the short axis direction by a first lens, a second lens, and the third lens. The fourth lens condenses a beam having a top hat distribution at the front focus position onto the irradiated surface.

A layer on a substrate is laser annealed by pulses in a plurality of laser beams formed into a uniform line beam. The laser beams are partitioned into a first set of beams and a second set of beams. The second set of beams is incident onto the layer from a smaller range of angles than all of the beams combined. Pulses in the beams are synchronized such that pulses in the first set of beams are incident on the layer before pulses in the second set of beams. Pulses in the first set of beams melt the layer and pulses in the second set of beams sustain melting.

The present application relates to a light pulse signal processing system. A to-be-measured signal light source generates a to-be-measured signal light pulse, and the to-be-measured signal light pulse is transmitted to a cylindrical lens. The to-be-measured signal light pulse is converted into a to-be-measured signal light pulse having a spatial angle chirp by the cylindrical lens, and is outputted and is incident into a pair of long mirrors at different angles. The to-be-measured signal light pulse incident at different incident angles is delayed by the pair of long mirrors. A cluster of to-be-measured signal light pulses with a corresponding repetition rate is outputted to a beam combining mirror, and is combined with a cluster of reference light pulses by the beam combining mirror. A light signal analysis device analyzes the combined cluster of light pulses.
