Abstract: In this study, we demonstrate a high-power ytterbium-doped fiber laser (YDFL) based on laser diodes (LDs) directly pumping scheme. Tandem pumping and LD direct pumping are two common schemes ...

Small projects and repairs are no match for this portable welder.

GWEIKE introduces a portable laser welding machine and multifunction M-Series system to help manufacturers improve ...

Abstract: In this study, an improved heterodyne demodulation quartz-enhanced photoacoustic spectroscopy (IHD-QEPAS) gas sensor is demonstrated, employing an erbium-doped fiber (EDF)-ring laser for the ...
