HOLO/OR Diffractive Beam Sampler

HOLO/OR Diffractive Beam Samplers are diffractive optical elements (DOE) used to monitor high power lasers. When an input laser beam passes through the beam sampler as the zero order, two higher order side beams with low energy are produced as the -1 and +1 orders. These higher order beams can then be directed onto a detector to monitor the profile and power level of the laser beam. HOLO/OR Diffractive Beam Samplers are available with Zinc Selenide (ZnSe) substrates for use with CO₂ lasers.

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
