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:
