Dual Wavelength Band Antireflective Coating

This coating allows two center wavelengths radiation pass through the substrate with high transmission. This coating is often used in frequency doubling systems or the other multi-laser output systems, such as the Nd:YVO₄ laser (1064nm) and its second harmonic generation (532nm) green laser.
