HOLO/OR Diffractive Vortex Phase Plates are diffractive optical elements (DOE) that convert an input beam from a Gaussian profile to a donut-shaped energy ring. These optical elements are composed of spiral-phase steps, the pattern of which controlling the phase of the transmitted beam. An optical lens can be used to focus the generated energy ring while maintaining the beam profile. HOLO/OR Diffractive Vortex Phase Plates are designed to work with collimated single mode (TEM00) Gaussian input beams, converting them to a TEM01 axially symmetric mode. These phase plates are available with designs for 532nm Nd:YAG lasers and 1030nm Yb:YAG lasers. Typical applications include solar coronagraphs, astronomy, high resolution microscopy, laser welding, optical tweezers, and quantum optics.

Note: Diffractive optical elements are not intended for use outside of their design wavelength. Diffractive optical elements will have decreased performance if their surfaces become dirty from oil or other substances. It is recommended to always use gloves or finger cots when handling these optics.

Edmund Optics offers a range of diffractive optical elements from HOLO/OR for laser applications, including:

  • Diffractive Diffusers: used to convert an input laser beam to a defined shape with homogenized distribution
  • Diffractive Beamsplitters: used to split an input laser beam into a 1D array or 2D matrix output
  • Diffractive Beam Shapers: used to transform a nearly-Gaussian laser beam into a defined shape with uniform flat top intensity distribution
  • Diffractive Beam Samplers: used to transmit an input laser beam while producing two higher order beams that can be used to monitor high power lasers
  • Diffractive Axicons: used to transform an input laser beam to a Bessel beam that can be focused to a ring
  • Diffractive Vortex Phase Plates: used to convert a Gaussian profile beam to a donut-shaped energy ring
