“…The significant NLO properties of novel organic and inorganic compounds have been expanded and have allowed promising applications in various photonic developments, optical communications, biomedical imaging, etc. 38,39 Our group extensively investigated various original molecules such as phthalocyanines, [40][41][42] porphyrins, [43][44][45] porphycenes, 46 and diverse nanoentities 31,[47][48][49] in terms of their NLO response to understand the interaction of NLO materials with fs and pico-second ( ps) laser pulses. These extensive studies revealed the interesting nonlinearity of these novel synthesized compounds, making them potential candidates for numerous applications such as optical switching and optical limiting.…”
