Fig. 1. PL emission spectra of KDP crystal with different flux irradiations measured from (a) 200 to 400 nm and (b) 400 to 800 nm.
Fig. 2. PL emission spectra of KDP crystals with different flux irradiations measured from 400 to 800 nm: (a) Retired; (b) 9.0 J/cm2; (c) 11.5 J/cm2. The black solid lines represent the experiment spectra, the red dotted lines represent the simulated spectra, and the blue lines represent the Gaussian fitting curve.
Fig. 3. PL emission spectra of KDP crystals with different flux irradiations were measured from 200 to 400 nm: (a) Retired; (b) 9.0 J/m2; (c) 11.5 J/m2. The black solid lines represent the experiment spectra, the red dotted lines represent the simulated spectra and blue lines represent the Gaussian fitting curve.
