Low saturable intensity

Enhanced stability of nitrogen-sealed carbon nanotube saturable absorbers under high-intensity irradiation.

Due to their broadband saturable absorption and fast response, carbon nanotubes have proven to be an excellent material for the modelocking of fiber lasers and have become a promising device for the implementation of novel laser configurations. However, it is imperative to address the issue of their long-term reliability under intense optical pulses before they can be exploited in widespread co...

Low Intensity Pulsed Ultrasound (LIPUS)

The application of ultrasound energy at much lower levels than is the current clinical norm is starting to gain ground as a therapeutic possibility. Clearly the applied energy is the same, it is the ‘dose’ which is different – most importantly, the intensity (W/cm) – which is MUCH lower – typically 2 or 3 times lower than the lowest setting on most regular clinical machines, with the most commo...
