The laser is perhaps the most important optical device to be developed in the past 50 years. . 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. Laser safety Retraining. Laser safety at Purdue University is managed by the Laser Safety Officer (LSO) and Radiological and Environmental Management (REM). Purdue’s laser safety program is overseen by the Laser Safety Committee (LSC). Laser Safety Training Overview. 2. Rowan University / Department of Environmental Health and Safety.
