“…When an NLO crystal is irradiated by a laser, the thermal load in the crystal for a long time might result in the losses of output laser power and degradation of beam quality. , It is noteworthy that the thermal conductivity is closely related to the latent heat of the crystal during crystal growth and is a main index influencing the morphology and size of the crystal . The thermal conductivity κ can be obtained by the crystal specific heat, C p , and thermal diffusivity, α T , according to the equation below: The thermal diffusion coefficients of KBLABF crystal were measured along the a -axis and c -axis in the 25–450 °C temperature range.…”

Beryllium-free nonlinear optical (NLO) crystal K3Ba3Li2Al4B6O20F (KBLABF) is a newly reported promising candidate in the generation of the significant UV coherent light. A 17 × 12 × 8 mm3 bulk single crystal is successfully grown with an optimized flux molar ratio. The crystal specific heat increases from 0.65 J·g–1·°C–1 to 0.96 J·g–1·°C–1 with the increasing temperature. Meanwhile, the a-direction thermal conductivity of KBLABF is 1.11 W·m–1·K–1 at 25 °C, which is also equivalent to that of the famous NLO crystal β-BaB2O4 (1.25 W·m–1·K–1). The KBLABF crystal has moderate Vickers hardness along the a-axis and c-axis (165.1 HV0.1 and 257.7 HV0.1, respectively), which indicates it is easy to be cut and polished. Remarkably, the laser damage threshold of KBLABF is 3.32 GW·cm–2 (1064 nm, 8 ns), which even exceeds those of some famous commercial NLO crystals. This result demonstrates that KBLABF is suitable for high-power NLO applications. This work will establish the foundation for the future NLO applications of the KBLABF crystal.

“…Rathnakumari [21] has grown Mo 6+ and Fe 3+ doped KTP crystals using the flux method, and that found was able to reduce the conductivity of the KTP crystals by 1-2 orders of magnitude. Sadhasivam [22] used the flux method to grow KTP crystals by doping Yb 3+ , which effectively reduced the conductivity of KTP crystals. The results showed that the conductivity of KTP crystals can be reduced by using the flux method for doping of KTP crystals.…”

As an electro-optical crystal with excellent properties, potassium titanyl phosphate (KTP) has high conductivity limits electro-optical applications. In this experiment, Rb-doped KTP crystals were grown by the hydrothermal technique of micro-doping and sustained-release, the crystal structure was determined by XRD, the presence of Rb in the crystals was explored by EDS, and the role of Rb in the crystals was investigated by Raman technique. Frequency-dependent dielectric constants were studied at room temperature, which decreases sharply at low frequencies. The variation of the conductivity of the crystals at different temperatures was investigated, and it was found that the room temperature conductivity of the KTP crystals, which were micro-doping by large ionic, was able to drop to 10−13 S/cm, which is about two orders of magnitude lower than that of the pure KTP crystals.
