Optical resonator

Build efficient CO2 lasers at wavelengths besides 10.6 µm with band-selective resonator optics that “lock” operation at 9.3 µm, 9.4 µm, 9.6 µm, or 10.2 µm. These resonator optics utilize advanced thin-film technology to deliver high reflectance at the desired operating wavelength while suppressing laser action at 10.6 µm. This maximizes output power and stability at the wavelength of choice. Coherent band-selective resonator optics can be fabricated for any CO2 laser transition and are designed for both standard gas mixes and isotope fills.
