Semiconductor laser pump sources, especially those with a wavelength of 969nm, have become the preferred choice for high-power/high peak energy disc lasers due to their reduced quantum losses and heat generation.The 3000W 969nm fiber coupled semiconductor laser system launched by BWT uses 800 μ m NA0.22 fiber to output flat top optical energy distribution, combining lightweight and excellent optic...
The new photonic integrated circuit technology based on lithium tantalate has improved cost efficiency and scalability, making significant progress in the fields of optical communication and computing.The rapid development of photonic integrated circuits (PICs) has revolutionized optical communication and computing systems, combining multiple optical devices and functions on a single chip.For deca...
An interdisciplinary research group, including the German synchrotron radiation accelerator DESY and the Helmholtz Institute in Jena, Germany, reported that invisible gratings made of air not only are not damaged by lasers, but also maintain the original quality of the beam.The relevant research has been published in Nature Photonics under the title of "Acousto opt modulation of gigawatt scale las...
Recently, Haemantics Corporation, which focuses on providing innovative medical solutions with proprietary optical technology, announced that the company has reached a final agreement. According to the agreement, Haemonics will acquire all outstanding shares of Canadian fiber optic sensor manufacturer OpSens for CAD 2.90 per share.This is an all cash transaction with a fully diluted equity value o...
A project at NIST has developed a new way to monitor and assess 3D printing of metals.Finding and correcting defects inadvertently created inside a 3D printed part is one of the biggest challenges for metal printing, commented NIST. But getting a close look at the printing operation as it's underway is not easy.As well as the toxicity of the raw materials, there can be a risk of combustion or expl...
