1064nm laser mirror with 633nm tracer

  Spectral Optics offers hybrid laser mirrors that provide high reflectivity and durability at both Nd:YAG and doubled YAG wavelengths at either 0° or 45° and also afford the convenience of system alignment using using visible wavelength tracer lasers.
  The dual wavelengths (1064nm & 532nm) YAG laser mirrors give R>99.0% at both wavelengths. Tracer laser options for either 633 nm HeNe and 670 nm diode laser wavelengths can be provided. Reflectivity is > 99.0% at the laser wavelength and >80.0% at the tracer wavelength. Damage threshold considerations for visible and near-IR wavelengths are similar to standard mirrors. For high-power applications in the UV, consult a Spectral Optics engineer to determine the best solution.
