Title: The Innovations of Elliot S. Wachman
Introduction
Elliot S. Wachman is a notable inventor based in Dewitt, NY (US). He has made significant contributions to the field of laser technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
Wachman's latest patents include a femtosecond ultraviolet laser using ultra-thin beta barium borate. This invention features a laser pulse generator that utilizes intracavity doubling in an ultrathin beta barium metaborate crystal to produce femtosecond pulses in the ultrashort ultraviolet wavelength range. The generator incorporates a colliding-pulse passively mode-locked ring dye laser, which propagates a pulsed beam of primary laser light in a cavity. The primary light beam operates at a repetition rate of 108 Hz and has a pulse width in the femtosecond range. The crystal is strategically placed in the cavity, allowing the primary beam to strike one crystal surface at Brewster's angle and propagate through the crystal at its phase-matching angle. The primary beam and its second harmonic are emitted from the opposite surface, with the harmonic wave maintaining the same repetition rate and substantially the same width as the primary beam, but at half its wavelength.
Another significant patent is for a broadly tunable high repetition rate femtosecond optical parametric oscillator. This invention provides femtosecond light pulses in the infrared wavelength band. The oscillator features an internally mounted thin crystal of KTiOPO4, which is synchronously pumped by femtosecond pulses from a colliding-pulse passively mode-locked dye laser. The rotation of the crystal allows for variation in the wavelength of the oscillator. Additionally, prisms within the oscillator cavity control group velocity dispersion to limit pulse width, while a feedback network stabilizes the oscillator by varying the length of the cavity in response to spectral changes.
