Dispersing prisms

Main features

 

  • Fabricated from high-quality UV fused silica, BK7, SF11 glasses
  • Both AB 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

  • Description
  • Standard specifications

4Lasers standard uncoated isosceles dispering prism 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 them at Brewster angle, therefore p-polarized light losses are extremelly small.
