Liquid pulse laser ablation is a reliable and versatile technique for producing metal nanoparticles in solution. Its advantages include no reducing agent, simple operation, high purity, no need for purification steps, and environmental processing conditions, making it the preferred method for traditional metal NP preparation.The widespread adoption of PLAL in scientific and industrial research has...
Scientists from the Federal Institute of Technology in Lausanne (EPFL) have successfully miniaturized a powerful erbium-based erbium laser on silicon nitride photonic chips. Due to the large volume and difficulty in shrinking of typical erbium-based fiber lasers, this breakthrough is expected to make significant progress in optical communication and sensing technology.Since the 1960s, lasers have ...
In the constantly evolving field of technology and data communication, researchers have made significant breakthroughs: developing a continuous wave O-band quantum dot semiconductor comb laser for wavelength division multiplexing optical interconnection. With its impressive performance characteristics, this development is expected to completely change the way we manage and transmit data, especiall...
