| Abstract | Organic crystals find applications in frequency doubling, frequency mixing, electro optic modulation, optical storage and optical communications. The organic compounds with electron rich (donor) and deficient (acceptor) substituents, provide the asymmetric charge distribution in the electron system and show large nonlinear optical responses. NLO crystals should meet several requirements, such as large phase matchable nonlinear optical co-efficient, a wide optical and chemical stability and a high damage threshold [13]. A majority of organic crystals have their absorption in the blue region and some of them have a cut-off wavelength lower than 450 nm. This indicates the possibility of reduced conversion efficiency of SHG due to self-absorption of materials when using a semiconductor laser with 800 nm band [142, 143]. Recently, there has been a search for newer organic NLO materials with blue light transmittance [144]. |
