Economy Nd: YAG Laser Harmonic Separator
Nd:YAG laser harmonic separators are precision dichroic optical components designed for efficient separation of fundamental and harmonic wavelengths in high-power laser systems. Featuring high-reflectance coatings for target wavelengths and high-transmission coatings for passband wavelengths, combined with anti-reflection coatings on the rear surface to minimize loss and ghosting, they deliver excellent spectral selectivity, low wavefront distortion and high laser-induced damage threshold. Suitable for 0° or 45° incidence, these components are widely used in laser frequency conversion, harmonic separation, beam combining and ultrafast laser systems.
