Typically, for lasers in optical communication systems, waveguide designs are used to achieve a single transverse mode. By adjusting the thickness of the surrounding area of the cladding layer and the etching depth of the ridge in the ridge waveguide device, a single mode device can be obtained. The importance of lasers is reflected in the following aspects:A chip without ridge waveguide design an...
Recently, Coherent, an American laser system solution provider, announced that all of the company's ultra fast laser business, including the manufacturing of all picosecond and femtosecond lasers, will be unified in one place: the Ultra Fast Center of Excellence in Glasgow, Scotland.Previously, Coherent's Ultra Fast Center of Excellence located in Glasgow was already a state-of-the-art mass produc...
Scientists from the Hanover Laser Center (LZH) in Germany are studying two laser based processes for producing load adapted hybrid solid components.From a transaction perspective, mixing semi-finished products can help save materials and production costs, but if the components that need to be replaced are made of expensive materials, these materials need to meet high requirements in future use, su...

Beijing, April 1st (Reporter Liu Xia) - The world's most powerful laser has been activated recently. On March 31st, the Physicist Organization Network reported that the system can enable laser pulses to reach a peak of 10 terawatts (1 terawatt=100 terawatts=1015 watts) within 1 femtosecond (1000 trillions of a second), which is expected to promote revolutionary progress in multiple fi...
