Knight Optical’s – Laser Thin Film Polarisers
04 Sep 2022
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:
We do not just provide stock components; we also excel at providing custom optical components made to our customer’s specifications. Knight Optical can provide single and dual-wavelength polarisers, as well as broadband polarisers suitable for femtosecond applications.
Our typical custom capabilities include dimensions from 5mm to 180mm, and coating wavelengths from 300nm to 5000nm. However, please do not hesitate to contact us if your requirements fall out of these ranges as we are always expanding our capabilities.
With offices in the UK and USA, Knight Optical is well equipped to provide our customers with a quality service and components, and with a Metrology Laboratory and Quality Assurance department, you can be assured your components meet their required specifications.
