Core key technologies

Ultra-narrow linewidth fiber DFB fiber laser

Distributed feedback is used to generate ultra-narrow linewidth single-frequency lasers, and unique packaging technology is used to improve the long-term frequency stability of single-frequency lasers, ensuring that the laser frequency never mode-hops.

High power and high efficiency frequency conversion

High-power and high-efficiency fiber laser frequency doubling technology expands the fiber laser output wavelength to the visible light and ultraviolet bands.

High Power Narrow Linewidth Fiber Amplifier

With unique high-efficiency stimulated Brillouin scattering suppression technology, the output power of single-frequency single-transverse mode fiber laser reaches hundreds of watts.

High performance pulsed fiber laser

The unique nonlinear technology is used to realize the saturable absorber effect. The laser pulse stability is extremely high, and it can withstand high and low temperature working environments of 0-45°C. It has excellent mode-locking self-starting performance and can achieve continuous startup of 100,000 times.
