Shielding effect of the smoke plume by the ablation of excimer lasers [PDF]

BMC Ophthalmology, 2018
Background Shielding and scattering effect of the smoke plume column ejected from the laser ablated material is a well-known phenomenon. Debris evacuation system of the excimer laser equipment removes these particles, but insufficient air flow can result

Laser Active Optical Systems (LAOSs) for Material Processing [PDF]

Micromachines
The 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).
