Evidence of slow-light effects from rotary drag of structured beams

open access: yesNew Journal of Physics, 2013
Self-pumped slow light, typically observed within laser gain media, is created by an intense pump field. By observing the rotation of a structured laser beam upon transmission through a spinning ruby window, we show that the slowing effect applies ...

Deploying diode laser in periodontics: An evidence-based review

open access: yesAdvances in Human Biology, 2018
Lasers have completely changed the concept of dental treatment since three and half decades of 20th century. After the invention of ruby laser by Maiman in 1960, laser has become the most magnetizing technology in dentistry.

Study of ruby laser beam interaction with glass [PDF]

open access: yesFME Transactions, 2013
This paper presents the results of the ruby laser light interaction with glass surface. The investigation was conducted in order to determine the maximum density of laser light energy (λ = 694.3 nm, t = 30ns) that can be safely applied in different laser

Microbubble‐Controlled Delivery of Biofilm‐Targeting Nanoparticles to Treat MRSA Infection

open access: yesAdvanced Functional Materials, EarlyView.
Here, an effective strategy using microbubble (MB)‐controlled delivery of biofilm‐targeting nanoparticles (BTNs) for removal and therapy of methicillin‐resistant Staphylococcus aureus (MRSA) biofilm infections is introduced. In vivo delivery of MB with BTN is demonstrated to silence key bacterial genes involved in biofilm formation (icaA), bacterial ...
