An improved discharge technique for excimer lasers [PDF]

open access: yes, 1990
The further development of discharge excimer lasers depends upon a better degree of control over the discharge stability. A problem is the large difference between the breakdown and steady-state voltage which requires a time dependent impedance of the ...

Investigation in the degradation of CaF2 outcouplers in excimer lasers operating at 193 nm

open access: yes, 2022
Paper 71321AIn many applications of ArF-excimer lasers, a specific degradation effect is observed for the CaF2 outcoupling windows which starts assumedly at the rear surface and results in a characteristic damage morphology.

Shielding effect of the smoke plume by the ablation of excimer lasers

open access: yesBMC 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
