Lithium Triborate (LBO) is a nonlinear optical crystal with a combination of unique features:

 

  • Wide transparency region
  • Broad Type 1 and Type 2 non-critical phase-matching (NCPM) range
  • Small walk-off angle
  • High damage threshold
  • Wide acceptance angle
  • High optical homogeneity

LBO crystal is perfectly suitable for various nonlinear optical applications, like frequency doubling and tripling of high peak power pulsed Nd doped, Ti:Sapphire and Dye lasers, pptical parametric oscillators (OPO) of both Type 1 and Type 2 phase-matching, non-critical phase-matching for conversion of CW and quasi-CW radiation.  

 

We offer:

  • LBO crystal of length up to 50 mm and aperture up to 40×40 mm
  • Thin crystals down to 10 µm thickness
  • AR, BBAR, P-coatings
  • Different mounting and repolishing services
