Product Description
Titanium-doped sapphire (Ti:Al 2 O 3 ) laser crystal is the core material for femtosecond ultrashort pulse laser and petawatt-level high-power laser technology. The crystal has tunable wavelength (660-1200nm) and wide emission bandwidth ( About 600nm), large emission cross-section, high thermal conductivity, excellent physical and chemical properties, etc., is currently the most widely used tunable laser crystal and the most important working medium for ultra-fast, ultra-intense and high-power
Main Features
Broad wavelength tunability
Broad absorption pump band
Excellent output efficiency
Short excited state lifetime (3.2 mm)
Narrow clamp width
high damage threshold
