Latest Patents

Dutta holds a patent titled "Method for controlling configuration of laser induced breakdown." This invention provides a method for laser-induced breakdown of a material using a pulsed laser beam. The material is characterized by a relationship of fluence breakdown threshold (F.sub.th) versus laser beam pulse width (T) that exhibits a distinct change in slope at a predetermined laser pulse width value. The method involves generating a beam of laser pulses, each with a pulse width equal to or less than the predetermined value. The beam is focused to a point at or beneath the surface of the material where breakdown is desired. This technique allows for the production of features smaller than the spot size and Rayleigh range due to enhanced damage threshold accuracy in the short pulse regime. Dutta has 1 patent to his name.
