Titanium Sapphire Laser Crystals
Titanium doped sapphire(Ti3+:Al2O3) is widely used for tunable
lasers and femtosecond solid-state lasers.It was first used as a
gain medium in 1986, and till now, it is still the best material
for ultrashort pulse generation. The substrate-sapphire has good
physical and optical properties. High thermal conductivity and good
alleviating thermal effects provide the usability for high power
• Best materials for ultrashor pulse generation
• Tunable range from 600-1100nm
• High gain
• Could be pumped by shor pulse flash lamps
• Good physical and optical propertiesProperties of Ti:sapphire or Cr3+
• Sapphire (monocrystalline Al2O3) has an excellent thermal
conductivity, alleviating thermal effects even for high laser
powers and intensities.
• The Ti3+ ion has a very large gain bandwidth (much larger than
that of rare-earth-doped gain media), allowing the generation of
very short pulses and also wide wavelength tunability(typically
using a birefringent tuner). The maximum gain and laser efficiency
are obtained around 800 nm. The possible tuning range is ≈ 650 nm
to 1100 nm, but different mirror sets are normally required for
covering this huge range, and exchanging mirror sets is a tedious
task. (The number of mirror sets required can be reduced by using
ultrabroadband chirped mirrors.)
• There is also a wide range of possible pump wavelengths, which
however are located in the green spectral region, where powerful
laser diodes are not available. In most cases, several watts of
pump power are used, sometimes even 20 W. Originally, Ti:sapphire
lasers were in most cases pumped with 514-nm argon ion lasers,
which are powerful, but very inefficient, expensive to operate, and
bulky. Other kinds of green lasers are now available, and
frequency-doubled solid-state lasers based on neodymium-doped gain
media are widely used. The pump wavelength is then typically 532
nm, with a slightly reduced pump absorption efficiency compared
with 514 nm.
• The upper-state lifetime of Ti:sapphire is short (3.2 μs), and
the saturation power is very high. This means that the pump
intensity needs to be high, so that a strongly focused pump beam
and thus a pump source with high beam quality is required.
• Despite the huge emission bandwidth, Ti:sapphire has relatively
high laser cross sections, which reduces the tendency of
Ti:sapphire lasers for Q-switching instabilities.
