Defects of large-size KDP single crystals and their influence on degradation of the optical properties

Raman spectral characterization of NH 4 H 2 PO 4 single crystals: Effect of pH on microstructure

“…pH is an important crystal growth parameter, affecting the stability of solution and crystal defects. Several studies have been conducted on KDP crystals [5][6][7][8]. Sharma et al [9] investigated the effect of pH on the growth kinetics of the pyramidal and prismatic faces of KDP; maximum growth was observed at a stoichiometric pH of 4.2.…”

“…Sharma et al [9] investigated the effect of pH on the growth kinetics of the pyramidal and prismatic faces of KDP; maximum growth was observed at a stoichiometric pH of 4.2. Because of the presence of one type of hydrogen bond in KDP crystals, it is relatively easy to investigate the effect of pH on the growth of KDP crystals [10][11][12][13][14][15][16]. Badrouj et al [17] reported the pH dependence of the growth of KDP crystals using Raman spectroscopy; a reasonably higher growth rate was observed in aqueous solutions that have been supersaturated at a temperature range 30-50°C and pH 3.2-5.4.…”

Rotary ultrasonic machining of potassium dihydrogen phosphate (KDP) crystal: An experimental investigation on surface roughness

“…Because of its unique properties, potassium dihydrogen phosphate (KDP) crystal can be widely used for parts of sonar and piezoelectric products [1], Q-switches [2], high speed photography shutters [2], electro-optical modulators [3], and frequency harmonic generation lens [4][5][6][7][8][9][10][11].…”

Effect of doping of KDP crystal with amino acid l-arginine on the strength properties and character of laser damage

“…This is due to a unique set of physical properties of group KDP crystals, in particular, their high transparency in a wide (ranging from the UV to near IR) spectral region, high laser damage resistance, good optical homogeneity combined with optical nonlinearity optimal for powerful high-energy laser systems. Moreover, the existing technologies make it possible to grow and mechanically treat large-size KDP crystals [2] . One of the methods for raising the efficiency of second harmonic generation (SHG) is introduction of organic molecules, e.g.…”
