In order to reveal the influence of oxidization on the properties of AlF3 films, single layers of AlF3 were deposited at different substrate temperature by thermo evaporation technique with or without oxygen injected into the coating chamber. The chemical composition, total stress, optical properties and laser damage resistance of samples were characterized. Comparative study indicates the AlF3 films prepared under higher oxygen pressure have more oxides which result from hydration process in atmosphere. The presence of oxides also reduces total stress and optical absorption of the fluoride coatings.

Kdp Crystals

Rapid growth processing of KDP crystals was improved by employing continuous filtration to eliminate bulk defects. The performances of the KDP crystals, including scattering defects, laser damage resistance and transmittance, were measured and analyzed. Compared with rapid-grown KDP without continuous filtration, the transmittance in the near-infrared was increased by at least 2%, almost all of ‘micron size’ defects were eliminated and ‘sub-micron size’ defects were decreased by approximately 90%. Laser damage testing revealed that the laser-induced damage thresholds (LIDTs), as well as the consistency of the LIDTs from sample to sample, were improved greatly. Moreover, it identified that ‘micron size’ defects were the precursors which initiated laser damage at relative lower laser fluence (4–6 J cm−2), and there was a lower correlation between smaller size scattering defects and laser damage initiation. The improved consistency in the LIDTs, attributed to elimination of ‘micron size’ defects, and LIDT enhancement originated from the decreased absorption of the KDP crystals.
