A Laser Triggered Synchronizable, Sub-Nanosecond Pulsed Electron Source

A laser excited, sub-nanosecond, pulsed electron beam system is described. The system consists of a high voltage pulser and a coaxial triggered spark gap. The liquid spark gap discharges into a pulse forming line designed to produce and maintain a flat voltage pulse of 1ns duration on the cathode of a photodiode. A synchronized laser is used to illuminate the photo-cathode to produce an electro...

Will Sub-Nanosecond Lasers Replace Nanosecond Lasers for Tattoo Removal?

With their short nanosecond pulse durations, Qswitched lasers have revolutionized the treatment of tattoos [1-3]. Nevertheless, the mechanisms for clinically observed tattoo clearance are still not well understood. Two mechanisms have been proposed: a) a thermal effect where tattoo particles are heated to sufficiently high temperatures to cause chemical changes within the particles and the surr...

Sub-nanosecond Arithmetic

The SNAP (Stanford Nanosecond Arithmetic Processor) project is targeted at realizing an arithmetic processor with performance approximately an order of magnitude faster than currently available technology. The realization of SNAP is predicated on an interdisciplinary approach and effort spanning research in algorithms, data representation, CAD, circuits and devices, and packaging. SNAP is visua...
