Technical Parameter

  Titanium doped Sapphire (Ti:Al2O3) laser crystal is the core material of femtosecond ultra-short pulse laser and watt-level high-power laser technology. The crystal has the advantages of being tunable at wavelength (660-1200nm), wide emission bandwidth (about 600nm), large emission cross section, high thermal conductivity and excellent physical and chemical performance. It is the most widely used tunable laser crystal and the most important working medium for producing ultra-fast and super-high-power laser operation. We can provide large diameter (Maximum diameter 260mm) Ti: Al2O3 laser crystals upon customer request.
