A Brief Introduction to Fiber Laser

A Brief Introduction to Fiber Laser
1. Working principle of fiber laser Light Source
The core part of a fiber laser is a fiber doped with rare earth elements (such as ytterbium doped fiber and erbium doped fiber). When the pump light source (usually a diode laser) enters the fiber through a coupler, the rare earth elements are excited and generate laser through stimulated radiation. Laser propagates and amplifies in optical fibers, and ultimately outputs through the end of the fiber.
2. Advantages of Fiber Laser Light Source
2.1. High beam quality: The beam generated by fiber lasers has high beam quality and low beam divergence angle.
2.2. High efficiency: The optical electrical conversion efficiency of fiber lasers is very high, usually between 30-50%.
2.3. Good heat dissipation performance: Fiber optics have a large surface area, which helps with heat dissipation and enables fiber lasers to operate continuously at high power.
2.4. Compact and sturdy: Fiber lasers have a compact structure and high stability and shock resistance.
2.5. Maintenance free: Fiber lasers typically have a longer lifespan and lower maintenance requirements due to their solid-state and sealed design.
2.6. Tunability: The wavelength and power of fiber lasers can be adjusted within a certain range to meet different application requirements.
3. Application of Fiber Laser Light Source
3.1. Minimally invasive surgery: Fiber laser Light Source can be transmitted into the body through optical fibers for minimally invasive surgery, such as endoscopic surgery.
3.2. Tissue cutting and coagulation: suitable for tissue cutting and coagulation in surgical procedures, reducing bleeding and accelerating healing.
3.3. Skin treatment: used for laser hair removal, skin regeneration, and removal of pigmentation lesions.
3.4. Ophthalmic surgery: High precision beams are suitable for retinal surgery and laser myopia correction surgery.
3.5. Tumor treatment: Laser Light Source is transmitted to the tumor site through optical fibers for photothermal therapy.
Fiber laser have become an indispensable tool in the medical field due to their high efficiency, high beam quality, good heat dissipation performance, and multifunctionality. When selecting and using fiber laser light source, it is necessary to ensure the performance, reliability, and safety of the equipment according to specific medical application requirements.
