    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. Ti:Sapphire crystals of North Optics are grown by the method of Temperature Gradient Technique (TGT), large-size (Dia.30x 30mm) Ti:Sapphire crystal absent of light scatter, with the dislocation density less than 102cm-2 could be provided. The TGT-grown sapphire crystal is characterized by the (0001) oriented growth, high doping level (a490= 4.0cm-1), high gain, and exceptional laser damage threshold.

    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.
