Lithium Triborate – LBO Crystals

LBO is a nonlinear optical crystal with combination of a number 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:

  • Frequency doubling and tripling of high peak power pulsed Nd doped, Ti:Sapphire and Dye lasers
  • Optical parametric oscillators (OPO) of both Type 1 and Type 2 phase-matching
  • Non-critical phase-matching for conversion of CW and quasi-CW radiation.  

EKSMA OPTICS offers:

  • 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-coating
  • Different mounting and repolishing services
