Abstract
Lasing Characteristics of High Quality Nd:YAG Crystals Grown by Temperature Gradient Technique are discussed. A Nd:YAG crystal of 05x50 mm in size was grown by a temperature gradient technique. It has good optical homogeneity (interference fringe number is zero) and an efficiency of 1% at 1 or 2 pps. It is easy to be operated in TEM sub 00 mode. Antireflective Coating has high efficiency at 1.06 micrometers. The error of the two-layer antireflective coating is analysed. It is shown that optical properties of the film composed of non-quarter wavelength stack are more stable that those of the film composed of quarter wavelength stack. The two-layer antireflective film has been made on K9 substrate and Ta2O5 and SiO2 used as coating material. Its reflectivity at one surface is lower than 0.03% and laser induced damage threshold is over 7 GW/cc (at 1.06 micrometer and 1 ns).
