BBO Crystal

  • Introduction

BBO Crystal


The BBO Crystal is a high-temperature phase of BaB2O4, is an excellent birefringent crystal an efficient NLO crystal for the second, third and fourth harmonic generation of Nd: YAG lasers, and the best NLO crystal for the fifth harmonic generation at 213 nm. Conversion efficiencies of more than 70% for SHG, 60% for THG and 50% for 4HG, and 200 mW output at 213 nm (5HG) have been obtained, respectively. BBO Crystal has been widely used in 2,3,4 or 5 harmonic generations for high power visible/UV sources, and optical parametric conversions for high power broadly tunable sources.


Advantages of BBO Crystals


  • Broad phase-matching range from 409.6 nm to 3500 nm
  • Extensive optical transmission from 190 nm to 3500 nm
  • Large effective second-harmonic-generation (SHG) coefficient
  • High damage threshold of 10 GW/cm2 for 100 ps pulse-width at 1064 nm
  • Wide temperature-bandwidth of about 55℃
  • Excellent mechanical and physical properties
