Ti:Sapphire crystals

26 Apr 2019

Titanium-doped sapphire (Ti3+:Al2O3) is a widely used transition-metal doped laser crystal. The Ti3+ ion has a very large gain bandwidth, that opens possibility to obtain very wide wavelength tunability realized in short pulse lasers. To obtain crystals with good optical quality Ti3+doping concentration should not exceed 0,25 at.%. Thus the crystals with thickness of several millimeters have to be used. The crystal is characterized by short upper-state lifetime and high saturation power. All these facts lead to necessity of strongly focused pump beam usage.

Main features

  • Excellent thermal conductivity
  • Broad gain bandwidth
  • Wide range of possible pump wavelengths (typically 532 nm)
  • Custom crystals available upon request

Application examples

  • Mode-locked lasers with ultrashort pulses
  • Multi-pass amplifiers and regenerative amplifiers
