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.
