System and Method for Laser Generated Corneal and Crystalline Lens Incisions using a Variable F/# Optical System with Aspheric Contact Interface to the Cornea or Rotating and Adaptive Optics

Abstract

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 in value that of the first F/#. The laser system further including an afocal optical system that is in the slow path and receives the laser beam from the optical switch 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 including 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 only in the case wherein the scanning laser beam is generated from the laser beam in the fast path. The laser system further including an aspheric patient interface device that receives a laser beam from the scan lens system.
