785 nm Narrow-Linewidth Lasers

The 785 nm line is the gold standard excitation for Raman spectroscopy in pharmaceuticals, forensics, and biological samples. By shifting into the near-infrared, 785 nm dramatically suppresses fluorescence background while remaining within high-efficiency silicon CCD/CMOS detector response. Models feature VHG wavelength stabilization, sub-picometer spectral drift, and high power stability.
