Shanghai Hanyu's 2.0um-band high-power quasi-continuous-wave (QCW) fiber lasers use a master oscillator power amplifier (MOPA) architecture. Optimizing amplifier pump power, gain-fiber length, and fiber coiling, together with Hanyu's proprietary temporal pulse-stabilization technology, increases output power while maintaining optimal beam quality without pulse distortion. Nearly ideal square pulses are maintained during millisecond-scale long-pulse operation. The MOPA design provides narrow spectral output (<0.7nm) and near-diffraction-limited output beam quality. These 2.0-band high-power QCW fiber lasers are suitable for industrial processing, scientific research, and biomedical applications, including laser pumping, transparent polymer welding, and surgical applications such as urology, urinary lithotripsy, and resection, ablation, vaporization, coagulation, and hemostasis in general surgery. The typical operating wavelength is 1940nm; any wavelength from 1900 to 2050nm can be customized on request.
