Title: John R. Harris: Innovator in Optical Fiber Technology
Introduction
John R. Harris is a notable inventor based in San Carlos, CA (US), recognized for his contributions to optical fiber technology. With a total of 3 patents, he has made significant advancements in the field, particularly in applications related to lasers.
Latest Patents
One of his latest patents is for a transport optical fiber for Q-switched lasers. This innovative optical fiber assembly features a clad optical fiber with an end-cap that focuses radiation into the fiber. A roughened portion of the fiber cladding allows any radiation that propagates in the cladding to escape, while a concave reflector directs the escaped radiation away from the fiber assembly. Additionally, the assembly includes a connector for linking the optical fiber to a laser, which features an air-cooled beam-dump for receiving the reflected radiation.
Another significant patent by Harris is a laser resonator assembly designed for diode-pumped solid-state lasers. This assembly comprises a glass planar support plate with at least two transparent mirror mounts bonded to it using a UV curable adhesive. The resonator mirrors are also bonded to the mounts with a similar adhesive, resulting in a structure that is easy to align and assemble while being cost-effective. The use of materials with a low coefficient of thermal expansion enhances thermal stability, and the transparent mirror mounts provide improved stability while allowing the transmission of laser radiation.
