Laser Attenuators
Let's See What We Have Here Diffractive attenuators control the power of laser radiation using diffraction gratings. Since phase diffraction gratings do not absorb light they can be used for high-power laser radiation (CW, pulsed). Variation of grating parameters along the substrate results in variable transmission at a given wavelength.
Diffractive Variable Attenuators are based on binary optics technology. Attenuator manufacturing starts from computer design of two-dimensional diffractive gratings using proprietary Diffraction Optics Design Software. Master Grating mask is created using high-resolution laser photo plotters. Final manufacturing process is accomplished using lithographic methods including plasma etching.
Diffractive attenuators are designed for wavelength from deep UV till IR. Damage threshold for these high power attenuators is more than 250W/cm2 in CW and 1000 mJ/cm2 in 10ns pulses.
