Laser is a laser generating device and one of the core components in laser application equipment. As the core component of laser technology, lasers are strongly driven by downstream demand and have huge growth potential and broad application scenarios.

Optical coherence tomography is a low-loss, high-resolution, non-invasive medical imaging technology developed in the early 1990s. It combines optical technology with ultrasensitive detectors. Using modern computer image processing, OCT fills the gap in resolution and imaging depth between microscopes and ultrasound imaging. The imaging resolution of OCT is about 10~15 μm, which is clearer than that of intravascular ultrasound (IVUS), but OCT cannot image through blood. Compared with IVUS, its tissue penetration ability is lower, and the imaging depth is limited to 1-2mm.

Directly generating visible light from compact all-fiber lasers while maintaining high output characteristics has always been a research topic in laser technology. Here, Ji et al. proposed a method to develop dual-wavelength lasers using the excitation mechanism in holmium-doped ZBLAN fluoride glass fibers, and experimentally achieved high output performance of all-fiber lasers, especially operating in the deep red band under 640 nm pumping. Notably, a maximum continuous wave output power of 271 mW was achieved at 750 nm with a slope efficiency of 45.1%, which is the highest direct output power recorded in all-fiber lasers with a core diameter of less than 10 μm in the deep red band.

Compared with traditional oxyacetylene, plasma and other cutting processes, laser cutting has the advantages of fast cutting speed, narrow slit, small heat affected zone, good verticality of slit edge, smooth cutting edge, and many kinds of materials that can be cut by laser. Laser cutting technology has been widely used in the fields of automobiles, machinery, electricity, hardware and electrical appliances.
