期刊介绍：
Researching is owned by Chinese Laser Press (CLP), which is established by Shanghai Institute of Optics and Fine Mechanics and Chinese Optical Society in 2009. Nowadays, CLP publishes 11 journals and manages three online platforms. Journal publishing activities include both traditional and digital models, and the first journal can be traced back to 1964. The CLP Online Library includes the CLP journals and partnered ones in China, and provides literature and intelligence services for users. The product platform, named as OEShow, connects sellers and buyers of optoelectronics products. Researching (formerly known as The CLP Publishing) is featured with stable operation and leading technology, collects CLP journals and partnered optics and photonics journals, and provides readers an optical publishing platform with global influence. CLP is on the way of building a modern publishing group combining traditional business and digital publishing.
