“…Several reports in the literature have described the response of BBO crystals to high-intensity, ultraviolet laser beams, including thermal dephasing effects [11], operational lifetimes [12], and twophoton absorption [13]. Additional studies have focused on characterization of absorbing defects (both impurities and native colour centres) in BBO crystals [14][15][16][17][18][19][20][21][22][23][24]. These latter investigations have been preliminary in nature and have not provided detailed structural information about defect models, and they have not established direct connections between optical properties (e.g.…”

Silver ions have been diffused into single crystals of β-BaB2O4 (commonly referred to as BBO). The crystals were wrapped in silver foil and then held in air at 760°C for periods of time ranging from 1 to 7 h. This treatment resulted in Ag+ ions occupying both Ba2+ sites and interstitial sites within the crystal. After the diffusion, the crystal was irradiated at room temperature with 60 kV x-rays. Three distinct paramagnetic defects, one holelike and two electronlike, were produced by the x-rays and observed with electron paramagnetic resonance (EPR) at temperatures between 15 and 80 K. The Ag+ ions substituting for Ba2+ ions trapped radiation-induced holes and became paramagnetic Ag2+ ions. At the same time, interstitial Ag+ ions trapped electrons and became paramagnetic Ag0 atoms. There are two distinct versions of these latter centres. The EPR spectra of the Ag0 atoms show resolved hyperfine from the 107,109Ag isotopes, as well as from a neighbouring nucleus (possibly a Na+ impurity substituting for a Ba2+ ion). All the radiation-induced EPR signals were stable at room temperature for hours.

“…Similar procedure has also been done on other commercial crystals such as BBO. [ 28 ] Figure 1c shows the atomic resolution high‐angle annular dark‐field (HAADF)‐STEM image taken along the [110] axis. The STEM image also illustrates that the as‐grown MgSiP 2 crystal possesses the same structure as the previously reported one.…”

Superior infrared nonlinear optical (NLO) crystals are in urgent demand in the development of lasers and optical technologies for communications and computing. The critical challenge is to find a crystal with large non‐resonant phase‐matchable NLO coefficients and high laser damage threshold (LDTs) simultaneously, which however scale inversely. This work reports such a material, MgSiP2, that exhibits a large second harmonic generation (SHG) coefficient of d14≈d36 = 89 ± 5 pm V−1 at 1550 nm fundamental wavelength, surpassing the commercial NLO crystals AgGaS2, AgGaSe2, and ZnGeP2. First principles theory reveals the polarizability and geometric arrangement of the [SiP4] tetrahedral units as the origin of this large nonlinear response. Remarkably, it also exhibits a high LDT value of 684 GW cm−2, which is six times larger than ZnGeP2 and three times larger than CdSiP2. It has a wide transparency window of 0.53–10.35 µm, allowing broadband tunability. Further, it is Type I and Type II phase‐matchable with large effective SHG coefficients of deff,I ≈80.2 pm V−1 and deff,II ≈73.4 pm V−1. The outstanding properties of MgSiP2 make it a highly attractive candidate for optical frequency conversion in the infrared.
