Erbium-doped glass (Er Cr Yb Glass) Cr14
Erbium-glass lasers doped with Er³⁺, Yb³⁺ and Cr³⁺ provide useful coherent sources near 1.5μm, a relatively eye-safe spectral region, and are widely used in lidar and ranging, fiber communication and laser surgery. Despite major progress in InGaAs laser-diode pump sources, Xe flashlamps remain useful pumps for erbium-glass lasers because of their high reliability, low cost and simple system design. Approximately half of flashlamp radiation is emitted in the visible and near-infrared (IR), so Cr³⁺ is introduced into Yb-Er laser glass as a second sensitizer to use this energy.

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.
