LASER GENERATED CORNEAL AND CRYSTALLINE LENS INCISIONS

摘要

A laser system including a laser source that generates a laser beam and an optical switch that receives the laser beam and selectively sends the laser beam to either a fast path or a slow path, wherein in the fast path the laser beam has a first F/# and in the slow path the laser beam has a second F/# that is higher than that of the first F/#. The laser system also includes an afocal optical system that is in the slow path and an x-y scanner that receives either a first laser beam from the slow path or a second laser beam from the fast path. The laser system further includes a scan lens system that receives a scanning laser beam from the x-y scanner and performs a z-scan for the scanning laser beam from the laser beam in the fast path.
