LBO (Lithium triborate or LiB3O5) is a very useful nonlinear optical crystal material, especially for SHG THG of high-intensity laser radiation, intracavity SHG THG, deep-UV SFG and OPO applications.

 Advantages of LBO

  • Wide transparency,. High nonlinear coupling, good chemical and mechanical properties
  • Type I and type II non-critical phase-matching (NCPM) over a wide wavelength range.
  • High damage threshold(18.9 GW/cm2 for a 1.3ns laser at 1054nm)
  • Wide acceptance angle and small walk-off angle
  • High optical quality (homogeneity≈10-6/cm)

Applications of LBO

  • High power Nd:YAG and Nd:YLF lasers for R&D and military applications
  • Ti:Sapphire, Alexandrite and Cr:LiSAF lasers
  • Medical and industrial Nd:YAG lasers
  • Frequency-tripling (THG) of Nd:YAG and Nd:YLF lasers
  • OPA and OPO pumped by Eximer lasers and harmonics of Nd:YAG lasers
  • Frequency doubling (SHG) and tripling (THG) of high power Nd:YAP laser at 1.34μm.
