The 509 nm single-frequency continuous-wave (CW) laser represents a breakthrough in high-power, ultra-low noise laser technology. Utilizing an advanced injection-locked DFB seed laser combined with an external cavity Pound-Drever-Hall (PDH) resonant frequency doubling system, this laser breaks the record with an unprecedented 101.3 W output power and an ultra-narrow linewidth of 21 kHz.
It serves as the ideal, high-performance pump and excitation source for cutting-edge quantum and precision engineering applications.
