Ti:Sapphire
Titanium-doped sapphire (Ti:Sapphire) is a high-performance synthetic crystal material with excellent comprehensive properties. Its chemical formula is Ti³⁺:Al₂O₃, and it is formed by doping titanium ions (Ti³⁺) into the main component of sapphire (Al₂O₃). It has a hexagonal crystal system structure with a density of 3.98 g/cm³, a melting point of up to 2040℃ - 2050℃, a Mohs hardness of 9, a thermal conductivity of 52 W/m/k, and exhibits excellent physical properties. Its color typically presents a light red with a distinct purple tint, and the depth of the red color is related to the amount of titanium doping. The tunable range of the laser wavelength of titanium-doped crystal is usually 650 - 1100 nm, with a peak wavelength of approximately 800 nm. It is one of the materials with the widest wavelength tunable range among currently available tunable laser crystals.

Nd:YVO4 is one of the most promising commercially available diode pumped solid state laser materials. It has high laser induced damage threshold and good mechanical in addition to optical properties. Its large stimulated emission cross-section and high absorption of pump laser make it a right crystal for pocket laser. Nd: YVO4 can produce IR green and blue laser by using minor different set-up. A broad absorption band centered at 808nm and favorable mechanical properties make Nd:YVO4 well suited for compact, efficient, high power diode-pumped lasers. Natural birefringence gives rise to a highly polarized output at 1064.3 and 1342nm.
