Title: The Innovative Contributions of Pliny S. Hawthorn
Introduction
Pliny S. Hawthorn is a notable inventor based in Vandalia, OH (US), recognized for his contributions to the field of laser technology. With a total of 2 patents, he has made significant advancements in solid-state laser systems.
Latest Patents
Hawthorn's latest patents include the development of a gadolinium vanadate laser, which is an intracavity frequency-doubled solid-state laser. This innovative device utilizes a Nd:GdVO.sub.4 laser gain chip to generate a beam of visible laser light, particularly in the green portion of the optical spectrum. The design features a back end defined by an entrance mirror and a front end with a mirrored surface. A laser diode generates pump light that is transmitted through the entrance mirror into the laser gain chip, which emits fundamental laser light at approximately 1063 nm. A frequency doubler chip positioned adjacent to the laser gain chip doubles the frequency of this light, producing harmonic laser light with a wavelength of around 532 nm.
Another significant patent is for a low-cost, low-power visible light solid-state laser. This compact, laser diode-pumped system includes an output coupler mirror forming the front end of the laser cavity, with a rear mirror at the back end. The design incorporates a frequency doubler chip adjacent to the laser chip, which doubles the frequency of the generated light, effectively halving its wavelength. The innovative bonding of the laser chip to the frequency doubler chip enhances the efficiency of the laser cavity.
