Non-polarizing plate beamsplitters
Our non-polarizing plate beamsplitters are a perfect choice for high-power, polarization-sensitive applications.
These products represent an alternative to non-polarizing beamsplitter cubes (NPBCs). Such cubes are usually chosen for convenient handling, but absorption in hybrid metal/dielectric coatings mean that NPBCs exhibit a power loss of approximately 10% and a low LIDT of approximately 0.3 J/cm².
With plate beamsplitters, we have these issues solved:
- the absorption in their dielectric coating is practically non-existent
- their LIDT levels exceed 6 J/cm²
Altechna designs and optimizes these beamsplitters according to any unique wavelength, split ratio and angle of incidence. For a quick solution, we offer standard products with a working bandwidth of several tens of nanometers.
For example, beamsplitters designed at 1025 – 1095 nm can be used with Yb:KGW, Yb:YAG, Nd:YAG, Yb:Glass and Nd:Glass lasers. Furthermore, GDD-compensated dielectric coatings are available for selected wavelengths.
