Title: The Innovative Contributions of Henry Shields
Introduction
Henry Shields is a prominent inventor based in San Diego, California. He has made significant contributions to the field of laser technology, holding a total of nine patents. His work focuses on developing advanced laser systems that have applications in various industries.
Latest Patents
One of Henry Shields' latest patents is a short pulse laser system. This innovative system generates short duration pulses, such as under five nanoseconds, at an energy level of up to a few milli-Joules per pulse. The system utilizes a laser crystal that is pumped by diode lasers. A resonator with at least two mirror surfaces defines a beam path that passes through the laser crystal. The beam path is periodically blocked by a first optical shutter, allowing pump energy to build up in the laser crystal. A second optical shutter blocks the light in the resonator except for short intervals, enabling the light pulse to make multiple transits through the resonator, increasing in intensity. An optical release mechanism then releases the pulse from the resonator.
Another notable patent is a solid-state laser system for ultra-violet micro-lithography. This system generates highly monochromatic laser radiation at specific wavelengths for advanced micro-lithography, particularly at 248 nanometers and 193 nanometers. The system includes at least one Nd:YAG laser that produces a 1,064 nm laser beam consisting of narrow-linewidth pulses of infra-red laser radiation. This radiation is then frequency doubled and tripled to produce pulsed laser beams at 532 nm and 355 nm, which are further processed to generate the ultra-violet wavelength for micro-lithography.
