Dual Wavelength Anti-Reflective Coatings(Part No: DAR)

Download PDF document

Dual wavelength antireflective coating is designed to provide very high transmission at two different wavelength. 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.
