The femtosecond laser emits ultra short optical pulses with a duration of less than one picosecond, reaching the femtosecond level (1fs=10-15s). The characteristics of femtosecond laser are extremely short pulse width and high peak intensity.Ultra short pulse trains can minimize residual heat, ensure precise material processing, and minimize incidental damage. Its high peak intensity can induce no...
Canadian researchers have developed a new 3D printing method called Blur Tomography, which can quickly produce micro lenses with commercial grade optical quality. The new method can make designing and manufacturing various optical devices easier and faster.Daniel Webber from the National Research Council of Canada stated, "We have intentionally added optical blurring to the beams used in this 3D p...
This month, German laser giant Trumpf completed an expansion project at its smart factory in Pasing, Austria. The opening ceremony was held in the presence of members of the Tongkuai Group family and representatives from the business and political circles. Over the past two years, Tongkuai has invested approximately 40 million euros in the expansion of the factory. The company has built two new...
Recently, Vector Photonics, a well-known surface coupled laser technology supplier in the UK, announced that the company has received £ 3 million in financing (including £ 1.667 million in equity investment and £ 1.27 million in additional research funding, equivalent to approximately RMB 27.63 million) to help commercialize its surface coupled laser technology.(Image source: Vector Photonics)Vect...
The well-known journal Optica published a paper in November 2024 titled "Near complete extraction of maximum stored energy from large core fibers using coherent pulse stacking amplification of femtosecond pulses"The authors of the paper were the University of Michigan, Lawrence Berkeley National Laboratory, Peking University, and the German Institute of Synchrotron Radiation.The specific technique...
