660nm Fiber Coupled 20W Power Multi-mode
Feature:
- 20W stable CW output, 660nm red wavelength
- 105μm fiber core, SMA905 connector
- Industrial-grade thermal management
Applications:
- Medical Aesthetics: Used for PDT photodynamic therapy, skin rejuvenation, and superficial vascular lesion removal.
- Industrial 3D Sensing & Machine Vision: Applied to high-precision 3D scanning, contour mapping.
- RGB Laser Display: Core red light source for laser projectors, commercial displays; delivers wide color gamut.
- Biomedical & Material Processing: For fluorescence excitation and precision marking, organic materials.

- Our high-power fiber-coupled diode laser systems are designed with a focus on small size, high brightness and high wavelength accuracy. In addition, its unique bias design ensures high stability and low noise.
- The laser source used in the system is a visible guided red laser with a wavelength of 660nm. This ensures that the system is not only powerful, but also highly accurate and reliable.
- In addition, the system is extremely compact, making it ideal for use in narrow or tight spaces where larger laser systems would not fit.
