Fiber-coupled lasers in medical use:
Fiber-coupled lasers are widely used in the medical field because they're stable, compact, and easy to integrate. By coupling the laser into an optical fiber, the light can be delivered precisely to the treatment area, which makes procedures more accurate and less invasive.
They're commonly used in:
- Soft tissue surgery, such as ENT, dermatology, gynecology, and dental treatments, for cutting and coagulation.
- Varicose vein treatment (EVLT/EVLA) with wavelengths like 1470nm or 1940nm.
- Laser therapy and pain relief, where low-power lasers help tissue repair and reduce inflammation.
- Urology and oncology, for applications like tissue ablation, tumor treatment, or stone removal.
Because fiber-coupled lasers can easily connect to handpieces or catheters, they're very flexible and reliable tools for many modern medical devices.
Applications of 640nm, 1470nm, and 1940nm Fiber-Coupled Lasers in the Medical Field:
The combination of 640nm, 1470nm, and 1940nm fiber-coupled lasers covers a wide range of medical applications, from visible light therapy to deep-tissue procedures. Each wavelength offers unique absorption characteristics that make it suitable for different types of treatments.
640nm (red light):
Mainly used for phototherapy, skin treatments, and wound healing. The red light penetrates tissue moderately and helps stimulate cell regeneration, reduce inflammation, and improve blood circulation. It's often used in dermatology and aesthetic medicine.
1470nm (near-infrared):
Well absorbed by water and fat, making it ideal for soft tissue surgery and endovenous laser treatment (EVLT). It provides precise cutting and excellent coagulation with minimal damage to surrounding tissues. It's also applied in ENT, gynecology, and lipolysis procedures.
1940nm (mid-infrared):
Strongly absorbed by water, suitable for highly precise ablation and vaporization of soft tissues. It's commonly used in endovenous laser ablation, urology (for prostate and bladder treatments), and minimally invasive surgery where high precision and limited penetration are needed.
By combining these three wavelengths, doctors can select the most appropriate one for each medical procedure, achieving better treatment results with less thermal damage and faster recovery.
