“…Where there is no improvement in LIDT after annealing, the substrate had already failed at a lower damage threshold and no further improvement was likely. From figure 6 (a), it should be noted that considerable variation in the absorption across the sample surface may indicate a significant content of inclusions or microstructure which could contribute heavily to the observed LIDT, and the related mechanisms discussed in detail in the Wood et al and Lowdermilk et al [5,6]. LIDT damage types include material only ablation (seen in the Nb 2 O 5 /SiO 2 RF sputtered coating, figure 7 (a)), coating loss and substrate damage (seen in the such as the ZrO 2 /SiO 2 RF sputtered ( figure 7 (b)) and substrate only damage such as (seen in the such as the ZrO 2 /SiN DC sputtered coating ( figure 7 (c)).…”

The Laser Induced Damage Threshold (LIDT) and material properties of various multi-layer amorphous dielectric optical coatings, including Nb 2 O 5 , Ta 2 O 5 , SiO 2 , TiO 2 , ZrO 2 , AlN, SiN, LiF and ZnSe, have been studied. The coatings were produced by ion assisted electron beam and thermal evaporation; and RF and DC magnetron sputtering at Helia Photonics Ltd, Livingston, UK. The coatings were characterized by optical absorption measurements at 1064 nm by Photothermal Common-path Interferometry (PCI). Surface roughness and damage pits were analyzed using atomic force microscopy. LIDT measurements were carried out at 1064 nm, with a pulse duration of 9.6 ns and repetition rate of 100 Hz, in both 1000-on-1 and 1-on-1 regimes. The relationship between optical absorption, LIDT and post-deposition heattreatment is discussed, along with analysis of the surface morphology of the LIDT damage sites showing both coating and substrate failure.

“…In NLO applications, physical properties play an important role for the practical performance of a crystal. , For example, the thermal properties, such as the thermal conductivity and the thermal diffusivity, have an important influence on the growth of high quality crystals, as the thermal mismatch along the different crystallo-physical directions can produce streaks or other defects. − For another thing, the laser damage resistance of crystals may strongly influence the service time of optical devices. , Therefore, it is meaningful to thoroughly investigate the physical properties of KBLABF for its NLO applications.…”

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.

“…Calculated Verdet constants ( c) [67] λ 3.9-18.5 [113] About the crystal KDP (together with its analogs DKDP and ADP) is one of the oldest nonlinear optical materials [8], [121]. It was widely applied in the first experiments made in the 1960s, and it is still in use, especially in the experiments on inertial-confinement fusion [122], where damage-resistant and wide-aperture SHG and THG crystals are needed.…”
