The pump source, gain material, and resonant cavity are the three elements that make up a laser. Due to the selective effect of the resonant cavity on the lasing frequency, multi longitudinal mode operation is one of the characteristics of fiber lasers based on traditional resonant cavity structures, manifested as periodic beat peaks in the radio frequency (RF) spectrum and periodic fluctuations i...
The European Southern Observatory (ESO) team has recently made significant breakthroughs in the field of interferometric measurement technology. With the help of four newly installed lasers at the Paranal Observatory in Chile, the research team has successfully created a guiding star, marking a new era in interferometric measurement technology.The successful generation of the laser guided star is ...
On March 28th, Marvel Fusion, a laser fusion company from Munich, Germany, announced the completion of a B+round financing of 50 million euros, bringing the total amount of this round of financing to 113 million euros. It is reported that the company's cumulative financing has reached 385 million euros, making it the largest fusion company in Europe in terms of financing scale. This capital incr...
Researchers at the Technion-Israel Institute of Technology have developed a coherently controlled spin optical laser based on a single atomic layer.This discovery was made possible by coherent spin-dependent interactions between a single atomic layer and a laterally constrained photonic spin lattice, which supports a high-Q spin valley through Rashaba-type spin splitting of photons of bound states...
