Knight Optical’s Laser Optics range include Thin Film Polarisers which separate the s- and p-polarised light with negligible absorbance within the coating for low loss performance. The laser thin film polarisers are optimised for 515nm and 1030nm design wavelengths, ideal for Ytterbium (Yb) doped lasers including diode-pumped solid-state lasers (DPSSL) and fiber lasers, as well as Nd:YAG lasers emitting at 1064nm. Currently, we stock thin film polarisers which work at either 45° or at Brewster angle (55.4°), both of which have been coated using ion beam sputtered (IBS) technology, creating a compact and durable coating, with a LIDT suited for ultrafast laser applications. Often used within a laser resonator to separate the different polarisation states and can be used as an alternative to polarising beamsplitter cubes or Glan-type polarising prisms. The following are the tolerances for the laser polarisers: Material::UV Fused Silica Diameter::+0/-0.1mm Thickness::+/-0.1mm Surface Quality: :< 20/10 Parallelism::< 3 arc mins Chamfer::0.2-0.4mm x 45 deg Coating S1::Rs > 99.9% & Tp > 98% @ Design W/L (515nm, 1030nm, 1064nm) Coating S2:::ARp < 0.1% @ Design W/L

As well as Knight Optical’s Low GDD Ultrafast Laser Mirrors, we can also provide broadband and wide-angle alternatives to cover more of a range of applications. Our Wide-Angle Laser Mirrors optimised for the fundamental and second harmonic (SHG) emissions of Ytterbium (Yb) doped lasers including diode-pumped solid-state (DPSS) and fiber lasers, and therefore have a design wavelength of either 515nm or 1030nm. They exhibit > 99.9% reflection when used between 0 to 45°. The Broadband Laser Mirrors work from 700-900nm ideal for applications using a Ti:Sapphire laser, again demonstrating > 99.9% reflection within this wavelength range. Their key features include: •Ion beam sputtered (IBS) coating which is compact and durable. •Reflection > 99.9% within their design wavelength range. •Broadband laser mirrors work at 45° •Exhibit minimal group delay dispersion (GDD) to prevent pulse broadening •High laser induced damage threshold (LIDT) •Precision flatness and surface quality to Material::UV Fused Silica Diameter::+0/-0.1mm Thickness::+/-0.1mm Surface Quality S1:< 10/5 for 12.7mm/25.4mm diameters Surface Quality S2::< 80/50 Flatness Clear Aperture::80% or specified aperture Parallelism::< 5 arc mins Chamfer::0.1-0.4mm Coating S1::R>99.9% @ 700-900nm, AOI 45°, |GDD Rs| < 20 fs2
