In Vitro Destruction of Pathogenic Bacterial Biofilms by Bactericidal Metallic Nanoparticles via Laser-Induced Forward Transfer

Nanomaterials, 2020
A novel, successful method of bactericidal treatment of pathogenic bacterial biofilms in vitro by laser-induced forward transfer of metallic nanoparticles from a polyethylene terephthalate polymeric substrate was suggested. Transferred nanoparticles were

Non-Destructive Measurement with Lasers.

The Review of Laser Engineering, 1999
In a photoelectron spectroscopy system, we have measured the spectra and the source diameter of laserinduced plasma soft x-rays. Furthermore, we have developed a TOF-XPS (Time of Flight-X-ray Photoelectron Spectroscopy) measuring system and obtained TOF-spectra with the x-rays.

Deterioration of Bismuth-Doped fiber lasers performance induced by blue and green laser light launched into cladding

Results in Physics, 2022
For the first time, we demonstrate the photobleaching process of bismuth-related active centers (BACs) induced by blue and green laser radiation launched into the cladding of an active fiber having the low-refractive index polymer coating. The changes in
