L-arginine-phosphate doped Potassium Dihydrogen Phosphate single crystals with 0.2…4.4 wt.% concentration in the solution were grown on a point seed by the method of temperature reduction. The grown KDP: LAP crystals were characterized by UV-vis spectroscopy, powder XRD analysis, differential thermal and thermogravimetric analyses, and second harmonic generation efficiency measurements. The mechanical and laser strength values of LAP-doped KDP crystals have been evaluated. Slight variation in the unit cell parameters of KDP:LAP has been reported. It has been shown that the efficiency of second harmonic generation conversion in KDP:LAP crystals was higher by more than 3-fold as compared to the corresponding values of pure KDP. The experimental results evidence the suitability of the grown KDP:LAP crystals for optoelectronics, and the study is helpful for further searching and designing of hybrid NLO materials.
