2026-06-03 Experimental sample information and 351 nm absorption coefficients of DKDP crystals doi:10.57760/sciencedb.38030 en This dataset contains the raw measurement data supporting the conclusion on "the influence of different growth processes and crystal sectors on the third-harmonic absorption coefficient" in the paper "Impact of Trace Metallic Impurities and Segregation Mechanisms on the Third-Harmonic Absorption of DKDP Crystals". It comprises 13 DKDP crystal samples, including conventional slow-grown (2 boules, pyramidal sector only) and point-seeded rapid-grown (3 boules, both pyramidal and prismatic sectors). For each sample, the growth method, parent boule ID, growth sector (pyramidal/prismatic), sample ID, and measured absorption coefficient at 351 nm are presented in tabular form.The absorption coefficient was measured using a UV-Vis spectrophotometer, calculated according to the Beer-Lambert law with correction for multiple internal reflections. Each value is the average of at least three repeated measurements, and the relative standard deviation (RSD) for all values is less than 2%.The data file is in CSV (comma-separated values) format and can also be opened with Excel. The file contains the following columns:Growth MethodParent boule IDGrowth SectorSample IDAbsorption Coefficient (cm⁻¹)This dataset can serve as a fundamental dataset for correlation analysis with the trace impurity ion content data of the corresponding samples (see Dataset 2), aiming to identify the key impurity ions that have the greatest impact on the 351 nm absorption coefficient of DKDP crystals at extremely low impurity concentrations.
