“…Also, from the spectrum it is observed that SCTC crystal has lower cut off wavelength around 240 nm and wide transparency window (240–800 nm) of SCTC crystal could be used for UV‐tunable lasers as well as transmission of blue and green harmonic frequency of Nd:YAG laser operating at 1064 nm. The observed cut off wave length of grown crystal is less than the other well known non linear optical crystals like BBO (193 nm) and LBO (159 nm), Ammonium pentaborate (APB) (180 nm), Glycine barium nitrate (GBN) (210 nm), Tryosine doped glycine (200 nm), L‐lysine acetate (236 nm) and γ‐glycine (231 nm) . Interestingly, the result of grown crystal SCTC crystal encourages second harmonic generation and the absence of absorption in the region 240–800 nm is an advantage for NLO applications and also suggesting its use in optoelectronics devices …”
