High Energy Polarizing Beamsplitter (PBS) Cubes: production, principle, alternatives, customization
How High Energy PBS Cubes are made?
First of all, right-angle prisms are polished. Then, entrance and exit surfaces are coated with multilayer dielectric anti-reflective (AR) thin film coating and specially designed polarizing coating on hypotenuse of one of the prisms. After that, cubes are optically contacted (bonded) without any cement (no epoxy glue!). After manufacturing cubes are tested and stocked or shipped to Alien Photonics customers.
How High energy PBS cubes work?
PBS cubes for High Energy applications are designed to separate high power laser beam polarizations into S and P components. The p-polarized light is transmitted along the same direction as incoming unpolarized beam and s-polarization is reflected perpendicular to incoming beam. This separation is done by polarizing coating which is applied on hypotenuse on one of the prisms.
Alternative components for High Energy PBS cubes
Probably closest interchangeable component is thin film plate polarizer at 45 deg. However, with some additional adjustments high contrast Brewster’s type TFP polarizer can be used as well. If laser power is low or medium, and pulses are low energy, Alien Photonics Standard PBS Cubes can be used. If broad wavelength range is needed we recommend Broad band PBS Cubes.
Custom High Energy PBS cubes
Alien Photonics offers wide range of wavelengths, sizes and other characteristics. High energy dual-band, tri-band cubes are available upon request. Incidence angle is not normal (0 deg.)? Just let us know what your requirements are and we will help you with custom angle optimization.
High Energy Polarizing Beamsplitter (PBS) Cubes for lasers, research and other applications
PBS cubes for High-Power laser cutting machines
Alien Photonics optical bonded PBS cubes are designed are designed to split and combine beams, enabling precise material processing with enhanced efficiency and reduced thermal stress on the laser cutting machine.
High Energy PBS cubes for research and development (R&D)
Alien Photonics High Energy PBS cubes fit very well in various laboratories. As current research is aimed to more powerful lasers, these cubes can be an excellent component for laser-material interaction under high-intensity research at universities and institutes across the world.
PBS cubes for high power laser spectroscopy
High Energy PBS cubes in spectroscopy setups enable high-power laser beams to interact with samples without compromising the systems integrity. This allows material analysis under extreme conditions (e.g. high temperature).
High Energy PBS cubes for ultrafast laser amplification systems
In ultrafast lasers, Alien Photonics High Energy PBS cubes allows precise management of laser beam polarization to optimize amplification process. This is very important in high peak-power and precise devices, such as medical femtosecond lasers for surgery. Alien Photonics just like to kindly remind you that cubes have higher dispersion than 45 deg. TFP or brewster TFP polarizers.
