yag laser for spider veins Yttrium Aluminum Garnet rod    

Erbium doped Yttrium Aluminum Garnet (Er:Y3Al5O12 or Er:YAG) combines various output wavelength with the superior thermal and optical properties of YAG. Er:YAG is a crystal material with a wide pump band of 600 - 800 nm,and the Er:YAG lasers typically emit light with a wavelength of 2940 nm, due to the strong water and hydroxyapatite absorption at this wavelength It commonly used in medical applications such as surgery, cosmetic dermatology, and in many other laser applications, to where water is present. Low doped Erbium YAG have been studied as an efficient means to generate high power and high energy 1.6 micron 'eye-safe' laser emission thru 2 level resonant pumping schemes. In these systems, fiber or diode lasers pump the ~1.5 micron4I14/2>4I13/2 absorption band, where non-radiative coupling between stark levels allows 1.6 micron laser emission with quantum efficiencies in excess of 90%.
