Latest discoveries and innovations
Science and Technology Daily News December 13, 2013 (Reporter Shu Hongfu) The reporter learned from the recent China Graphene Standardization Forum held in Taizhou, Jiangsu that the world's first commercial graphene femtosecond fiber laser developed by Taizhou Juna New Energy Co., Ltd. Fiphene was launched, setting two world records for graphene femtosecond fiber lasers with the shortest pulse width (105fs) and the highest peak power (70kW).
The application fields of femtosecond fiber lasers are very broad, including scientific research applications such as laser imaging, holographic spectroscopy and ultrafast photonics, as well as fine processing of laser materials, laser medical treatment (such as eye surgery), lidar and other fields. The core device of the traditional femtosecond fiber laser, the semiconductor saturable absorption mirror (SESAM), is prepared by a semiconductor growth process, and the cost is very high, and the technology is monopolized by foreign countries.
In the field of femtosecond fiber lasers, graphene is considered to be the best material to replace SESAM. The 2010 Nobel Prize winner in physics wrote an article predicting that graphene femtosecond fiber lasers are expected to be industrialized around 2018. To achieve real industrialization, it is necessary to solve a series of key technologies such as high-quality graphene preparation, large-scale low-cost graphene transfer, graphene-optical field strength interaction, graphene saturable absorber packaging, and laser power stability control. After years of continuous research, Taizhou Juna New Energy Co., Ltd. has successfully overcome these key technologies, and took the lead in realizing the commercialization of graphene femtosecond fiber lasers. The main performance indicators are higher than similar products, with high cost performance and strong performance. market competitiveness.
The product is named Fiphene, a combination of the words Fiber (optical fiber) and Graphene (graphene). Taizhou Juna New Energy Co., Ltd. plans to use Fiphene as a platform to launch more graphene fiber laser products to push the application development of graphene forward.
