Fiber for Laser Removal of Vascular Lesions JG-02
Laser treatment of vascular lesions uses selective photothermolysis: hemoglobin absorbs selected wavelengths, converting light into heat, damaging endothelial cells, and closing vessels. Fiber types: silica commonly delivers energy effectively; multimode/single-mode choices depend on lasers and treatment needs. Effects: generally considered safe/effective for selected lesions such as port-wine stains/hemangiomas, with individual variation and possible repeated sessions. Device parameters vary with treatment, including laser type, power, frequency, and pulse width. Example: diode, 30W, 1~20Hz, 50ms, affecting efficacy/safety. Typical fiber structures: 1. Fiber—high-purity silica core, lower-index cladding for total internal reflection, and protective plastic coating. 2. Connector/tip—clinical shapes include flat tips for spreading energy over surface lesions or focusing tips for depth; connectors/adapters join devices. 3. Adapter/interface—safe attachment/removal, stable energy delivery, device compatibility, and optical alignment. 4. Control system—though outside the fiber, adjusts wavelength, pulse duration, intensity, and specialized-fiber output. Different designs share these basic structures for precision, robustness, effective treatment, and safety. Some devices also require special filters/mirrors to couple beams and safeguards against unabsorbed light.

Beveled Fiber Lens Optical Fibers Raysung
Beveled fiber lenses mainly fall into two categories. One has bevel angles of 6°～10° to prevent surface-reflected light from causing interference or damage on its return path. The other has angles of 40°～50° or greater, changing the optical path or producing large-angle total reflection. It can also increase the fiber's light-receiving area to admit more light. Main applications include fiber lasers, fiber-optic communications, conventional optics, and fiber sensing.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
