Red 638nm 700mW High Power Fiber-Coupled Laser Module for Medical Treatment

Core Technical Advantages for Medical Applications

• 638nm Red Laser Medical Optimization: Hemoglobin and mitochondrial chromophores highly absorb the 638nm wavelength, making it ideal for tissue stimulation, anti-inflammatory therapy, and wound healing. It penetrates 2-8mm into soft tissue (adjustable via power control) without damaging superficial cells, balancing therapeutic depth and tissue safety—critical for targeted treatments like acne reduction, pain management, and scar remodeling.

• 700mW High Power for Efficient Therapy: With stable CW output, the 700mW high power delivers concentrated energy to accelerate cellular metabolism, promote blood circulation, and reduce inflammation. It shortens treatment cycles (e.g., 3-5 sessions for mild acne, 6-8 sessions for chronic pain) while minimizing patient discomfort, outperforming low-power modules in clinical treatment efficiency.

• Fiber-Coupled Precision Transmission: This fiber-coupled laser module can pair with medical-grade silica fiber (core diameter 200/400/600μm, numerical aperture NA=0.22), ensuring lossless laser energy transmission (coupling efficiency ≥85%). The fiber enables flexible, minimally invasive delivery—reaching narrow or hard-to-access treatment sites (e.g., joint spaces, facial creases) with pinpoint accuracy.
