Guangzhou HUARENYIHE Special Optical Fiber Technology Co., Ltd. (HRYH for short) was established in July 2012 in the Science City of Guangzhou High-tech Development Zone, with 700 square meters of office and scientific research and production fields. Relying on the Special Optical Fiber Research Center of South China Normal University, HRYH is committed to the R&D of special optical fibers and their application products and to having the R&D results industrialized. So far, research results HRYH has made include optical fiber transmitting CO2 laser energy, broadband mid-infrared optical fiber, high nonlinear microstructured optical fiber, and rare-earth doped micro-structured optical fiber. HRYH is now the only team in China that has developed optical fiber transmitting CO2 laser energy successfully. In industry, HRYH mainly focuses on the upgrading and transformation of CO2 laser fiber computerized embroidery machine (patent number: ZL201220747448.6) and embroidery machine as well. Through being exhibited and exchanged on Laser World of Photonics China, Dongguan Textile Machinery Exhibition and Canton Fair, as well as comprehensive promotion at home and abroad, customer area scope of CO2laser fiber computerized embroidery machine expands from Dongguan, Foshan and Shantou of Guangdong province to Zhejiang and Jiangxi of China and even India and Pakistan. Meanwhile, HRYH continues to promote technological improvements, accelerates the development of light beam integration technology, develops high pow
