December 18, 2018, Mainz, Germany - Edmund Optics® (EO), the premier provider of optical components, announces the TECHSPEC® Nd:YAG Harmonic Separators. These beamsplitters are used to separate the common harmonic wavelengths of an Nd:YAG laser. The precision mirrors are designed for a wide range of demanding Nd:YAG laser applications.
TECHSPEC® Nd:YAG Harmonic Separators are dichroic mirrors used for separating the harmonic, frequency-doubled beam from the pump beam, which is often outside the laser resonator. The frequency doubled light is reflected to nearly 100%, while most of the pump light is transmitted.
TECHSPEC® Nd:YAG Harmonic Separators have a beamsplitter coating on the first surface, which reflects at least one wavelength and transmits another. The beamsplitter coating features greater than 95% transmission. The second surface has an anti-reflective coating to minimize losses from reflection. Designed for integration at 45° angle of incidence, the harmonic separators are manufactured using a precision λ/10 fused silica substrate that offers excellent optical and thermal performance and stability, along with a surface quality of 10-5. The RoHS compliant mirrors have a thickness of 6,35 ±0,20 mm, plate construction, and a clear aperture of greater than 85%.
TECHSPEC® Nd:YAG Harmonic Separators are available in multiple wavelength configurations for maximum system design flexibility. Fourteen models offer diameters of 12,70 mm and 25,40 mm at common Nd:YAG wavelengths of 1064 nm, 532 nm, 355 nm and 266 nm. TECHSPEC® Nd:YAG Harmonic Separators are in-stock and available for immediate delivery.
