Figure 6. TG/DTA spectrum of LKS crystal.
X-ray diffraction analysis confirms the grown crystal
belongs to hexagonal system. The optical transmittance
study shows the crystal has good transmittance in the
entire visible-NIR region and wide band gap. The Kurtz
and Perry powder SHG method confirm the SHG effi-
ciency of LKS is 1.6 times that of KDP and phase-
matching property. The mechanical property of the mate-
rial was studied by Vicker’s hardness measurement.
