Lithium Niobate (LiNbO3) Crystals

铌酸锂(LiNbO3)广泛应用于Nd:YAG、Nd:YLF和Ti:Sapphire激光器的电光调制器和q开关,以及光纤调制器等。横向调制主要用于LiNbO3晶体。

此外,LiNbO3晶体还广泛用于波长1um和1064nm泵浦的光学参量振荡器(OPO)以及准相位匹配(QPM)器件的倍频器。

Main Features

  1. Large Electro-Optic (E-O) coefficients 
  2. Large Acousto-Optic (A-O) coefficients 

Typical Applications

  1. Frequency doublers 
  2. Optical parametric oscillators (OPO) 
  3. Quasi-phase-matched (QPM) device 
  4. Q-switches and modulator
