LASER is actually an acronym for Light Amplification by the Stimulated Emission of Radiation. . the active medium is glass denatured by Neodymium ions(Nd +3) (active ions) with doping rate up to (6%). The color of the crystal is purple (8). dimensions of the crystal are from a few microns to (2 cm) length and the diameter (6-10 m). The Pumping using the flash lamp). with an efficiency not exceeding (1.5%) or using a semiconductor laser with an efficiency of up to (70%). It works with a system of quadrupole levels and it dose need good cooling. Group 6. MSOD . 613. January 2014. Relevance to OD. Why Knowledge. of . Group Stages and Development Matters.
