High Power Polarizing Beamsplitters

PBSHP/PBSHPQ

Polarization beam splitter spec Polarization beam splitter specially designed for pulsed lasers ially designed for pulsed lasers such as Nd-YAG lasers and Yb lasers. such as Nd-YAG lasers and Yb lasers.
High Power Polarizing Beamsplitters have more laser durability c High Power Polarizing Beamsplitters have more laser durability compared to our standard ompared to our standard Polarizing Beamsplitters (PBS).

Optics & Optical Coatings
  • Polarizing beamsplitters split a monochromatic beam entering at zero degrees into p-polarization as transmitted and s- polarization as reflected.
  • Four surfaces of the cube are coated with narrowband multi-layer anti-reflection coating.
  • The losses of input beam of these products are minimized because of no absorption resulting from the dielectric coating.
  • For cube beamsplitters, unlike plate beamsplitters, beam deviations of transmitted beams and ghosts rarely occur.
