Ammonium dihydrogen phosphate (ADP) crystals have higher fourth harmonic generation (FHG) efficiency than deuterated potassium dihydrogen phosphate (DKDP) crystals, because of the higher nonlinear optical coefficient. However, the narrower full-width at half-maximum (FWHM) temperature bandwidth and poor thermal stability limited the application in the noncritical phase-matching (NCPM) FHG. In this article, ADP and a series of deuterated ADP (DADP) crystals are grown through point-seed rapid growth method to investigate a feasible experimental condition on improving ADP crystals' thermal stability for NCPM FHG application. The deuterium doping experiment results indicate that the 60% DADP crystal could accommodate more laser-induced heat capacity during FHG processing and could achieve higher FHG output, but with poor thermal stability. Therefore, 60% DADP crystal's FHG stability measured by air indirect heating method. About 7% more stable FHG output is obtained than direct heating by copper, which is more suitable for FHG stability of ADP/DADP crystals.

Revealing the hydrogen bonding paradigm is critical to clarify the formation mechanism of hydrogen bonded materials. The nucleation process of a typical nonlinear optical crystal, KH 2 PO 4 , is identified by in situ molecular vibration spectroscopy, which effectively demonstrates the oriented role of hydrogen bonding in local structure engineering. On the basis of the vibrational evolution of hydrogen bonds, the partition of different periods in the formation of crystalline KH 2 PO 4 from aqueous solution becomes clear. In KH 2 PO 4 aqueous solution, there are hydrated status, (H 2 PO 4 − ) n aggregations, and prenucleation clusters. The prenucleation clusters exist in the solution with a metastable status over a period of time, and then they will transform into crystalline ones within a short time. Two distinct roles of P−O•••H−O−P hydrogen bonding in the formation of crystalline KH 2 PO 4 have been distinguished. At the initial stage of aggregation formation, P−O bond in H 2 PO 4 − group guides the P−O•••H−O−P hydrogen bonding, leading to the H 2 PO 4 − that retains C 2v symmetry, whereas P−O•••H−O−P hydrogen bonding guides the twist and rotation of H 2 PO 4 − groups in prenucleation clusters, promoting the local structural evolution of (H 2 PO 4 − ) n from C 2v to D 2d and the formation of crystalline KH 2 PO 4 nuclei. The present work deepens the hydrogen bonding effect that can warrant much space to adjust the chemical bonding environment in constructing crystallographic frames.

“…In this study, ADP crystals were grown in a dened crystallographic direction (q ¼ 90 , F ¼ 45 , which is the direction of NCPM) in an aqueous solution using the point seed rapid growth method. 25,26 Ex situ atomic microscopy (AFM) measurements were implemented to observe the prismatic growth micro-morphology of ADP. Moreover, Cr 3+ was added to the growth solution to study the effects of Cr 3+ on this growth direction as Cr 3+ is a common impurity ion.…”

Herein, ammonium dihydrogen phosphate (NH 4 H 2 PO 4 , ADP) crystals were grown in a defined crystallographic direction (q ¼ 90 , F ¼ 45 ) in an aqueous solution using the point seed rapid growth method. Ex situ atomic microscopy (AFM) measurements were implemented to observe the prismatic growth micro-morphology of ADP and Cr 3+-doped ADP in the defined crystallographic direction. It was found that with the increasing supersaturation, the growth morphology changed in turn to elementary steps, macro steps, and 2D nuclei. Moreover, the differences between ADP and Cr 3+-doped ADP grown in the defined crystallographic direction have been discussed. The influence of Cr 3+ on the growth of ADP crystals has been explored.
