Mg:SLT/Mg:LN

SLT(Stoishiometric LiTaO₃)
    /MgSLT(MgO doped Stoichiometric LiTaO₃)

Sub-grain boundary-free stoichiomatric LiTaO₃ crystals were successfully grown.

• Low defect density （100times lower） 
• Wide transparent region （UV cut-off 20nm lower）
• Large EO and NLO constants （d33 >26.2pm/V）
• Small coercive field （<1～2kV/mm）
• High photorefractive damage threshold （>5MW/cm²@532nm, cw laser）
• High laser damage threshold （>2GW/cm²＠1064nm, pulse laser）
• There is almost no birefringence index
• No GRIIRA (Green Induced IR Absorpution)
• Subgrain boundary-free stoichiometric LiTaO3 crystals were successfully grown.
