LAP (DLAP)
Due to significant absorption in the near infrared in pure L-arginine phosphate monohydrate (LAP), deuterated LAP (DLAP) crystals have been grown using heavy water (D2O) as a solvent by a slow cooling technique. The growth conditions for the growth of monoclinic dLAP crystals are optimized by adjusting the growth parameters, such as pH, temperature etc. The grown crystals are morphologically compared with the pure LAP crystals. Deuterated L-arginine phosphate C6D14N4O2 · D3PO4 is a promising non-linear optical material having good non-linear coefficient, high damage threshold as compared to L-arginine phosphate(LAP) and potassium dihydrogen phosphate (KDP).

APPLICATIONS:
• Second, third and fourth harmonic generation from the fundamental radiation 1.06 µm
• Sum and difference frequencies generation in wide spectral range from UV to IR
