“…Rs = Is/I T0 (6) The dependence of the scattering ratio of Hf:Yb:Nd:LiNbO 3 crystals on exposure time is shown in Figure 5. Saturation scattering ratio (R S,sat ) and scattering time constant is represented by (τ), the intensity of the laser light passing through the lens by (I 0 ), the effective light incident upon the crystal by (I eff ), and the intensity of the light reflected by the crystal by (I R ); the approach to incidence of an effective exposure energy flow to the crystal (E r ) can be obtained from the following equations [28,29]:…”

“…In recent years, many methods have been used to improve the optical properties of crystals, in which doping anti-photorefractive ions are the most promising method [4]. It was demonstrated that anti-photorefractive ions, such as Mg, Sc, and In, can significantly improve the optical damage resistance of LiNbO 3 [5][6][7][8]. Zhen et al reported that In 3+ -doped Nd:LiNbO 3 can significantly improve the optical damage resistance [9].…”

A series of Hf:Yb:Nd:LiNbO 3 crystals with different [Li]/[Nb] ratios (0.946, 1.05, 1.20, and 1.38) were grown using the Czochralski method. X-ray diffraction phase results of the samples show that the LiNbO 3 doped Hf 4+ , Yb 3+ , and Nd 3+ only have a slight change in the lattice constant. The birefringence gradient of the HfYbNd4 sample measured using the birefringence gradient method was 3.3 × 10 −5 ∆R/cm −1 , which was the best optical uniformity. The optical damage resistance ability was measured using the light-induced scattering exposure energy flus threshold method. When the [Li]/[Nb] ratios in the melt achieve 1.38, the exposure energy achieves 120.74 J/cm 2 , which is approximately 87 times higher than HfYbNd1.
