High-Energy Broadband Mirrors

These super broadband mirrors (SBB) are ideal for beam-steering applications using both the fundamental laser wavelength and one or more harmonics within the same beam path. Because it is an all-dielectric design, they can handle the high laser powers of both CW and pulsed systems, without limiting the useful angle of incidence or sensitivity to varying states of polarization.

custom high energy laser mirrors

Custom mirrors are available on other flat and curved substrates. Contact us for details on stress-compensated mirrors for λ/10 surface flatness after-coating.
