In comparison to non-polarizing beamsplitter cubes, our plate beamsplitters feature outstanding performance. Cubes typically cause energy loss of at approximately 10 %, because of absorption in hybrid metal/dielectric coatings whereof typically laser induced damage threshold varies in range of approximately 0.3 J/cm2. Non-polarizing beamsplitting plates design comprises only dielectric layers, thus damage threshold is much higher and exceeds 6 J/cm2. Separation of polarizations Rs – Rp typically is lower than 5 %. Because of this feature beamsplitters are suitable for use with unpolarized light or light of any other state of polarization. Standard items have working bandwidth of several tens of nanometers, which makes it versatile. For example beamsplitters designed at 1025 nm - 1095 nm can be used with Yb:KGW, Yb:YAG, Nd:YAG, Yb:Glass, Nd:Glass lasers. For usage with femtosecond lasers, Altechna has designed beamsplitters at 800nm and 400nm, which do not influence pulse width, as coatings are GDD compensated. Non-standard wavelengths and sizes are available upon request.
