Laser Active Optical Systems (LAOSs) for Material Processing [PDF]
MicromachinesThe output energy of Laser Active Optical Systems (LAOSs), in which image brightness is amplified within the laser-active medium, is always higher than the input energy. This contrasts with conventional optical systems (OSs).
