Infrared (IR) Optics

Infrared optics are required for certain lasers emitting at long wavelengths – for example CO2 lasers working at 10.6 μm. Due to the high power levels, it is essential to reach very low absorption losses of laser optics. Similarly, many optical parametric oscillators and amplifiers emit light at long wavelengths, and this often in relatively broad wavelength regions, so that broadband infrared optics are required.
