Nonlinear responses and optical limiting behavior of fast green FCF dye under a low power CW He–Ne laser irradiation

Nonlinear Characterization of Safranin O Dye for Application in Optical Limiting

“…Optical limiting performance will be enhanced by coupling two or more of * corresponding author; e-mail: pouchasri@yahoo.com the nonlinear optical mechanisms. Excited state absorption (ESA) and reverse saturable absorption (RSA) are the most common mechanisms for the nonlinear optical behavior of organic materials [11]. Nonlinear optical effects can be employed for the design and performance of optical limiter [12][13][14].…”

Nonlinear optical studies of curcumin metal derivatives with cw laser

“…The results are summarized in Table1. The value obtained in the experiment is two orders higher than the value 1.2x10 -3 cm/W for C60 and C1A1Pc [10,19] and of the same order when compared to the value 2.8x10 -5 cm/W for Fast green FCF dye [20]. In general, the mechanisms involved in the nonlinear response can be divided into two groups, local and nonlocal.…”

Phthalocyanines for photonic applications: a new perspective

“…The magnitude of the third order nonlinearity measured were one of the highest reported in the cw regime till date. The nonlinearities in our molecules are at least two orders of magnitude higher than any of the reported molecules [76][77][78][79][80][81][82][83][84][85][86]. Table 4 summarizes the NLO data obtained from our studies and comparison with some of the potential molecules reported recently.…”
