Titanium-doped Sapphire (Ti:Sapphire) is one of the most prevalent laser crystals for tunable and ultrashort pulsed lasers with high gain and high power outputs. Shalom EO offers high-quality Ti:sapphire crystals grown using the Temperature Gradient Technique (TGT) with absorption from 1.0-4.0cm^-1 at 490nm. Shalom EO’s TGT-grown Ti:sapphire crystal is characterized by the (0001) oriented growth, featuring large figure of merit, high gain, broad gain bandwidth, while also exhibiting excellent thermal conduction, large laser cross-section, and exceptional laser damage threshold. Dislocation densities less than 10^2cm^-2 contributing to minimized light scatter can be obtained. 


Application Notes:

  1. The tunable wavelengths that cover a broad range from 700 to 1000nm make Ti:Sapphire an excellent substitute for dye lasers in many applications.
  2. Frequency-doubled by NLO crystals such as ultra-thin BBO, Ti:Sapphire can be used to generate UV and DUV (up to 193nm) laser with ultrafast pulses with pulse durations less than 10fs.
  3. Ti:Sapphire is also used as the pumping source of Optical Parametric Oscillation (OPO) to expand the tunable range.
