Lithium tantalate (LiTaO3, LT) single crystal is one of the most important ferroelectric materials because of its unique piezoelectric, acousto-optic, electro-optic, and nonlinear optical (NLO) properties combined with good mechanical and chemical stability [1, 2, 3, 4]. In recent years, the glasses embedded with active ferroelectric crystalline phases particularly from the perovskite family such as potassium tantalate niobate (KTa0.65Nb0.35O3) , lithium niobate (LiNbO3) , strontium titanate (SrTiO3) , and others  have immense potential for a variety of applications due to their high transparency, compositional variety, low cost of fabrication, and are good alternatives to single crystal counterparts. It is observed that when activated with rare earth (RE) ions, these NLO nanocrystalline glass-ceramic composites are of considerable importance because with diode laser pumping those can lead to very compact, portable, and easy maintenance Ultraviolet (UV)–Visible laser...
