Title: Joseph H Zarrabi: Innovator in Laser Technology
Introduction
Joseph H Zarrabi is a notable inventor based in Malden, MA (US). He has made significant contributions to the field of laser technology, holding a total of 2 patents. His work focuses on miniaturized laser systems that enhance performance and efficiency.
Latest Patents
Zarrabi's latest patents include the "Miniaturized intracavity frequency-doubled blue laser." This innovative device utilizes a pump source operating within a radiation band of 780 to 820 nm, such as a Ti:sapphire laser, to pump a gain medium comprising a crystal of neodymium-doped yttrium orthoaluminate (Nd:YAlO.sub.3). The result is a fundamental radiation with a wavelength of approximately 930 nm, which is subsequently frequency doubled using a nonlinear crystal, such as potassium niobate (KNbO.sub.3), to yield output radiation at a wavelength of 465 nm. Another significant patent is the "Miniaturized self-Q-switched frequency-doubled laser." This diode-pumped monolithic laser is fabricated from a self-doubling host material co-doped with two ionic species. One ionic dopant converts pump radiation to continuous radiation at a fundamental frequency, while the other acts as a saturable absorber to Q-switch the fundamental radiation, producing pulsed high-intensity green light.
