GA-509-DG
The GA-509-DG is a single-frequency, all-polarization fiber laser operating at 509 nm, designed for applications that demand high optical power, ultra-low noise, and excellent spectral purity. The system integrates a narrow-linewidth seed laser and a power amplifier, optimized for stable continuous-wave (CW) operation. With TEM₀₀ beam quality, sub-40 kHz linewidth, and high polarization extinction, the GA-509-DG is an ideal light source for laser cooling and trapping, optical lattices, nonlinear optics, and precision scientific applications.
