Optical limiting properties of carbon disulfide at 2.05μm wavelength

Several types of infrared sensors are based on sensitive focal plane arrays. In such sensors, the intensity will typically increase by a factor ~107 at the focal plane, compared to the intensity of the incoming radiation. Such arrays are thus vulnerable when illuminated with high-intensity laser pulses. One solution for protecting the array against such pulses is to use an optical limiter. We here present results where carbon disulfide (CS2) has been tested as an optical limiting material against high-energy laser pulses at 2.05 μm wavelength. © (2016) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
