Today, laser pointers for clinical use are mostly argon ion laser pointer, carbon dioxide lasers, and YAG lasers, but usually their beam quality is not high, they have very large volumes, require huge water-cooled systems, and they are very difficult to place and maintain. It is exactly what fiber lasers can add. Since water molecules have an absorption peak at 2 μm, using a 2 μm fiber laser as a surgical thing can achieve rapid hemostasis and avoid damage to the human body structure during surgery.
As the world’s largest industrial manufacturing country, the demand for fiber laser marking machines is huge, and it is expected that there will be more than 2,000 units per year. In the field of laser welding and cutting, with the successful development of fiber lasers with a kilowatt or tens of thousands of watts, fiber lasers have also been applied.
Mode-locked fiber green laser pointer with rare-earth-doped fiber as gain medium can breed ultra-short optical pulses with high repetition rate and pulse width on the order of picoseconds or femtoseconds, and its lasing wavelength falls in the best window for fiber optic communication In the 1.55 μm band, it is the aspiring light source for future high-speed optical communication systems. Now, mode-locked fiber lasers with repetition rates of 10 GHz and 40 GHz have been successfully developed. Once this communication network is deployed, the demand for this model laser will be huge.
