ABSTRACT:
An optical system and a optical information processing equipment utilizing the same are disclosed. The optical system comprises a laser diode and a hologram lens has an interference fringe prepared by the interference of a beam having substantially the same intensity distribution and/or phase characteristic as that of a laser beam emitted from the laser diode with a beam having a desired characteristic. The laser beam from the laser diode is irradiated on the hologram lens so that its characteristic is converted into the desired characteristic.
