Supercontinuum can be generated in many commonly used dielectric materials, otherwise known as bulk materials. The generation of SC in these bulk materials has been well documented and is easily achieved in an indoor laboratory setting. However, inducing SC generation (SCG) in an outdoor setting through atmosphere has not been reported as frequently. We conducted an outdoor experiment at DAC’s Electro-Optical Vulnerability Analysis Facility (EOVAF) laser range in July of 2023. An USPL was used to irradiate an optical collimating system several hundred meters from the USPL with several different bulk materials placed at its exit aperture using a spectrometer system to measure the SCG induced in the materials. After the outdoor experiment was completed, the spectrometer was calibrated using a quartz tungsten halogen (QTH) lamp. The calibration data were used to create a spectral response function which was applied to the uncalibrated spectral data of the SCG resulting in calibrated measurements of spectral fluence. |
