1. An ophthalmic laser delivery system for delivering a pulsed laser beam generated by a laser to a patient's eye, comprising:
a laser beam scanner for reflecting an input laser beam to generate one or more output laser beams and scanning the output laser beams in two orthogonal directions, the laser beam scanner including at least one micromirror array, the micromirror array including a plurality of micromirrors forming a two-dimensional array, the plurality of micromirrors capable of being individually controlled to rotate to different angles;
optics for directing the pulsed laser beam from the laser to the laser beam scanner as the input laser beam and directing the output laser beams from the laser beam scanner to the patient's eye; and
a controller coupled to the laser beam scanner, configured to control a rotation of each of the plurality of micromirrors of the at least one micromirror array to simultaneously form a plurality of focal spots of the laser beam in the patient's eye and to simultaneously scan the plurality of focal spots according to predefined scan patterns.
