Ion generation and loading of a Penning trap using pulsed laser ablation

New Journal of Physics, 2020
We investigated the production of aluminum and beryllium ions via pulsed laser ablation using 355 nm wavelength and 5 ns long laser pulses. The ablation threshold of Al ^+ and Be ^+ was measured to be 0.9 ± 0.1 (stat.) ± 0.3 (syst.) J cm ^−2 and 1.4 ± 0 ...

A modified model for laser-cornea interaction following the ablation effect in the laser eye-surgery

Beni-Suef University Journal of Basic and Applied Sciences, 2023
Background Laser corneal reshaping is a successful treatment of many refraction disorders. However, some physical demonstrations for the laser interaction with cornea are not fully explained. In the current paper, we present a modified model to precisely

Update on CO2 Laser Ablation of Polyoxymethylene [PDF]

, 2010
Polyoxymethylene (POM) propellants have been studied since the 1970's, and perhaps represent the most promising match of a propellant to the CO2 laser for laser propulsion studies.
