Details

Titanium doped Sapphire (Al2O3:Ti3+) is a popular crystal, used for making ultra short pulse solid-state or wavelength tunable lasers. These crystals combine supreme thermal and optical properties with broadest lasing range among other materials. Its indefinite stability and short lifetime, in addition to lasing over entire band of 660 to 1050 nm makes Ti:sapphire lasers suitable for variety of applications spanning from material processing to time resolved and multi-photon spectroscopy. Recent studies have showed that diode pumping using a blue diode (445 nm) can also be used for making Ti:Sapphire oscillators. That is expected to raise the next generation of Ti:Sapphire lasers.

InStockOptics offers Ti:Sapphire crystals precisely cut from a boule of large monocrystal. The crystal is grown using the Czochralski method, which includes steps of:

melting of Al2O3 material with low concentration of Titanium
inserting a seed crystal to the melt
pulling the crystal out of the melt in highly controlled environment
cooling down the boule in a strict thermal regime
annealing the boule under strongly reducing atmosphere in order to achieve good balance between Ti3+ and Ti4+ ions. That is how the Figure of Merit (FOM) is achieved 150 or more

Applications:

Ultra-short pulse lasers
High repetition rate oscillators
Chirped-pulse laser amplifiers
Multi-pass amplifiers
Wavelength tunable CW lasers
Pulsed X-ray generation

Features:

Large gain-bandwidth
Very large emission bandwidth
Excellent thermal conductivity
Short upper-state lifetime (3.2 μs)
High saturation power
Relatively high laser cross-sections
High damage threshold
Strong Kerr effect
