 Sharp Laser Corporation (SFL) Overview: The laser business of Sharp is primarily operated by Sharp Fukuyama Laser Co., Ltd. (hereinafter referred to as SFL), a wholly-owned subsidiary established through a spin-off by Sharp Corporation in April 2019. Headquartered in Fukuyama City, Hiroshima Prefecture, Japan, SFL specializes in the manufacturing of laser diodes and semiconductors.  

 I. Company Background and Development History 1. Parent Company and Origin Sharp Corporation, founded by Hayakawa Tokujiro in 1912, is one of Japan's eight major electronics manufacturers and is currently under the umbrella of Foxconn Technology Group. Since the 1970s, Sharp has ventured into the field of semiconductor light sources and is one of the pioneering companies globally to commercialize laser diodes, boasting over 60 years of experience in laser technology research and development and manufacturing.   2.  Establishment and Development of SFL - April 2019: Sharp spun off its laser business and established Sharp Fukuyama Laser Co., Ltd. (SFL) - July 1, 2021: SFL inherited the semiconductor manufacturing business of Sharp Fukuyama Semiconductor Company through merger and absorption, forming two core business divisions - Semiconductor Division and Laser Division - Business Positioning: Focusing on the research, development, production, and sales of high-power, high-quality laser diodes, while providing semiconductor packaging and testing services

II. Core Business and Product Lines 1. Core Products of the Laser Business Division Sharp's laser diodes cover the full spectrum range of near ultraviolet (UVA), blue light, green light, red light, and infrared, with power ranging from a few milliwatts to several watts. The packaging forms include various specifications such as TO-CA, TO-56, and TO-18, meeting the needs of different application scenarios.
