Components for the second harmonics of Nd:YAG and Nd:YVO4 Lasers
The harmonics of Nd:YAG and Nd:YVO4 lasers are widely used for materials processing as well as for measurement applications. Moreover, the second harmonic of the Nd:YAG laser is often used as pump source for Ti:Sapphire lasers. On these pages we introduce optics for 532nm: dual wavelength mirrors, separators, thin film polarizers and non-polarizing beamsplitters, but also cavity optics for compact diode pumped lasers of different configurations. All designs are calculated according to customer specification.
(a): HR(0°, 1064nm) > 99.9% + R(0°, 532 + 808nm) < 3%
(b): HRs+p(45°, 532nm) > 99.9% + Rs+p(45°, 808 + 1064nm) < 2%
The transmission of thin film polarizers for p-polarized light can be measured with high accuracy by a modified cavity ring down setup.
For common specifications of separators for the harmonics in the UV spectral range please see table on higher-harmonics. Please do not hesitate to contact us for separators or mirrors with other angles of incidence.
Coatings on Nonlinear Optical Crystals
for 532nm and 1064nm
Nonlinear optical crystals are the key elements for frequency conversion. LAYERTEC offers a variety of coatings on crystals like KTP and lithium niobate. For more information on coatings on crystals see pages 92 – 93 in our catalog.
