High reflectance at two separate wavelengths
These are useful extra-cavity mirrors which have a high reflectance at both the Nd: YAG/YLF fundamental wavelength and also a wavelength in the visible spectrum. They can be supplied to reflect the laser harmonic wavelength. Alternatively, they can be supplied to reflect a HeNe laser or diode laser alignment beam. For UV applications, because UV beam is invisible to the eye, it is desirable to use a co-linear alignment (HeNe) laser.
