Ti: Sapphire crystal

Ti: Sapphire crystal products, also referred to as titanium doped sapphire crystal, the chemical formula for Ti3+: Al2O3 is a good extensive performance of the changing steel doped laser crystal.
As a light-pumped solid-state laser crystal, Titanium doped sapphire is extensively used in the wavelengths of a tunable laser, a tunable variety of 650-1100 nm, a top at 800 nm, and also the wavelength of a tunable laser crystal vast.

The Ti3+ ion has a large gain transmission capacity, which opens up the opportunity of obtaining the large wavelength tunability accomplished in short-pulse lasers. Due to its high saturation power, titanium sapphire stones are normally used as lights, argon ion lasers, or regularly dual removal neodymium yttrium aluminum garnet lasers. Using the self-mode-locking technique, the Ti: Sapphire laser can serial output laser pulses with a pulse width of less than 6.5 fs, which is fairly narrow amongst all lasers directly output from the resonator. The laser beam can cover a large band from blue to deep ultraviolet with dual-frequency technology. The 193nm laser produced has been made use of in lithography machines.

The peak power of the laser pulse reaches a beat watt. The pulse width reaches 10s of seconds and also is the brightest light source known to humankind. The titanium sapphire crystal is like the "human heart" in the ultra-strong ultra-short laser device. Without it, the ultra-strong ultra-short laser can not be generated. The larger the size of titanium sapphire crystal, the more power is soaked up, and the higher the laser result power. The item has short on-state life and high saturation power, which can be used in the light, argon ion laser, or frequency double removal neodymium yttrium aluminum garnet laser.
