Dispersing prisms

Main features

 

  • Fabricated from high-quality UV fused silica, BK7, SF11 glasses
  • Input and output faces are optically polished (refer to the drawing)
  • Small losses for p-polarized light
  • Group delay dispersion adjustment of ultrashort pulses
  • Antireflective coatings, custom design, substrate material, and dimensions available upon request

 

Application examples

 

  • Compression of ultrashort laser pulses
  • Dispersion compensation in mode-locked lasers
  • Spatial separations of different spectral components

4Lasers standard uncoated isosceles dispersing prisms are fabricated from UVFS, BK7, SF11 optical glasses and offer different dispersive properties. Used in both intra- and extra-cavity setups for ultrashort laser pulse temporal manipulation. Their construction enables to use of them at Brewster angle, therefore p-polarized light losses are extremely low.
