Abstract
A laser system including a laser source that generates a laser beam and an optical switch that receives the laser beam and sends the laser beam to either a fast path or a slow path, wherein the F/# of the fast path is lower than the F/# of the slow path. The laser system includes an afocal optical system in the slow path and receives the laser beam from the optical switch and an x-y scanner that receives either a laser beam from the slow path or a laser beam from the fast path. The laser system including a scan lens system that 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 including an aspheric patient interface device that receives a laser beam from the scan lens system.
