Application
- Improving fourth harmonic generation performance by elevating the operation temperature of ADP crystal: This study highlights the enhancement of fourth harmonic generation in ADP crystals by manipulating their operational temperature, demonstrating a crucial application in optical technologies (Liu et al., 2024).
- Growth and Temperature Properties of the Phase-Matching Angle of 23% Deuterated ADP Crystal: This research explores the phase-matching properties of deuterated ADP crystals, critical for improving the efficiency of nonlinear optical devices (Sun et al., 2024).
- Comparison of hydrogen vacancies in KDP and ADP crystals: This paper uses a combination of density functional theory and experimental approaches to study hydrogen vacancies in ADP crystals, providing insights into the structural properties that influence their optical performance (Sui et al., 2019).
- Structural, spectroscopic, optical, dielectric and mechanical study of pure and l-Proline doped ammonium dihydrogen phosphate single crystals: This comprehensive study addresses how doping ADP crystals with l-proline alters their physical properties, suggesting applications in both optical fields and material science (Hasmuddin et al., 2014).
