BOULDER, Colo., March 11, 2009 – Alpine Research Optics Corp. has introduced a series of high-performance harmonic separators, optimized for use with high-power solid-state lasers. 

Alpine-Harmonic-Separators.jpgThe harmonic-separating dichroic beamsplitters are used for either splitting or combining the various harmonics (1064, 532, 355 and 266 nm) of Nd:YAG and Nd:YVO4 lasers. Both short-wave pass and long-wave pass designs are available.

Because of their combination of high-damage threshold and mechanical durability, these optics are suitable for demanding applications in semiconductor fabrication, display manufacturing, solar cell production and other micromachining tasks. 

The beamsplitter coatings are typically supplied on flat substrates, with a high-efficiency antireflection coating on the second surface. Designs for both 0° and 45° angles of incidence are available. Near-infrared and visible wavelength optics are provided on optical grade fused silica substrates, and optics for use with ultraviolet wavelengths are fabricated on UV grade fused silica substrates. Other standard specifications are λ/10 flatness at 633 nm and 10-5 scratch-dig surface quality. 

The devices are available through Saint-Gobain Crystals.
