Optical materials transparent in the CO₂ laser wavelength range have been evaluated regarding their suitability for components ultrashort-pulse (≤ a few ps), high-peak-power (≥ TW) long-wave infrared (LWIR) lasers. We provide values nonlinear refractive index (n₂) seventeen materials, and thresholds absorption eleven materials. Characterizations were performed using 2 ps pulse at λ = 9.2 μm. This paper methodically presents newly acquired data conjunction with existing literature on linear optical properties, establishing it as comprehensive reference designing LWIR systems.
