Fiber laser technology benefits
Fiber laser technology has a significant impact in medicine by enabling new applications. Their unique features and versatility allow use in diagnostic imaging and surgery. Despite lower power, they provide high accuracy.
Safety and usability
Fiber lasers enable safe, contactless procedures for patients. Medical staff find them easy to use due to their compact design.
Versatility in treatments
Different fiber lasers operate in unique ways and can be used for various treatments. The laser beam can be delivered continuously or in pulses. Adjusting the wavelength allows specialists to control the effect on tissue and achieve desired results. These parameters can be customized during manufacturing.
Most common applications of fiber lasers
Fiber lasers are used in several medical areas.
Medical diagnostics and imaging
Specialists can now detect various diseases by observing changes in molecular composition. For instance, endoscopic fiber catheters provide imaging diagnostics during artery bypass surgery.
Optical Coherence Tomography
Fiber lasers with broad spectra are used in OCT to capture cross-sectional diagnostic images.
Aesthetic Applications
Procedures like tattoo removal or skin resurfacing often use CO2 lasers. Recent studies show conventional fiber lasers can also be effective.
Laser Surgery
Laser surgery employs light beams for operations. When the laser hits the skin, it may reflect, scatter, or penetrate tissue layers. Certain areas absorb the light, causing tissue changes. Fiber lasers are often used to shrink or destroy tumors and seal small blood vessels to prevent bleeding.
Overall, fiber laser systems remain highly effective medical tools, trusted by specialists and patients alike.
