For Solid-State Lasers

A new series of high-performance plate polarizers from Alpine Research Optics (ARO) are optimized for use with Nd:YAG, Nd:YVO4 and Nd:YLF lasers operating at 1064, 1053, 532, 355 and 266 nm. These thin-film optics use a first surface coating to separate orthogonal polarizations with a high extinction ratio (≥200:1). They are designed to work at Brewster’s angle (typically 56° angle of incidence) and can be tilt-tuned (±3°) to optimize performance. These optics also feature a high transmission efficiency (≥96%) as well as excellent damage threshold and mechanical durability characteristics.

ARO’s standard polarizers are available on 28.6 mm x 14.3 mm x 3.2mm fused-silica substrates. The optics are specified to have λ/10 flatness and λ/8 wavefront distortion on transmission (at 633 nm) and a surface quality of 10-5. In addition to this catalog product line, polarizers with custom sizes, shapes and performance characteristics over the wavelength range of 266 to 1550 nm can be produced on request.

The optical performance and extended lifetime of these polarizers make them suitable in a wide variety of industrial uses, including micromachining and marking of metals, semiconductors, plastics and dielectrics in microelectronics, biomedical, automotive, avionics and research.
