High power, high extinction ratio separation of s- and p-polarization at Nd:YAG wavelengths; no angle tuning required. Designed to operate at the Brewster angle, these high performance polarizing cube beamsplitters offer ultrahigh transmission of p-polarized light with high extinction ratio; no angle tuning required. They are available from stock for high power use at Nd:YAG and Nd:YLF wavelengths. Other wavelengths available upon request.

Ion Beam Sputtered Thin Film Plate Polarizers operating at 56° balance high performance with ease of use.  These polarizers are coated using durable ion beam sputtering on UV-grade fused silica, resulting in ultrahigh transmission of p-polarized light and high laser damage threshold.  The proprietary IBS coating used eliminates the need for angle tuning and allows use over a wide acceptance angle, while operation at the Brewster angle enhances extinction ratio.  Impact to beam quality is minimal, with low transmitted wavefront error, low wedge, and high surface quality.
• High laser damage threshold (10 J/cm2 @ 1064 nm)
• High extinction ratio (> 1000:1 for 355 nm, > 5000:1 for 1064 nm)
• No AR coating needed on second surface when operated at 56 ± 3°
• Nd:YAG wavelengths standard; other wavelengths, sizes, and angles of incidence custom
