Class 1 Laser Classification correct answers - cannot emit laser radiation at levels that are known to cause eye or skin injury during normal operation -very low power or beam is fully enclosed Class 1M Laser Classification correct answers -incapable of hazardous exposure conditions during normal ops unless viewed with collecting optics (binoculars) -exempt from control measures, other than to prevent optical aided viewing -exempt from other forms of surveillance Class 2 Laser Classification correct answers -low power, emit in visible spectrum (400-700 nm) -not considered strong enough to damage eyes because a person will normally blink and look away if it enters their eyes (aversion response) Class 2M Laser Classification correct answers -potentially hazardous if viewed with collecting optics -upper limit on a continuous wave laser in this class is 500 mW Class 3R Laser Classification correct answers -intermediate powered, hazardous under direct and specular reflection viewing -can produce no more that 5 mW in the visible region Class 3B Laser Classification correct answers -hazarous under direct and specular reflection viewing -not normally a diffuse reflection or fire hazard operate between 5-500 mW for CW systems cannot produce radiation energy greater than 0.125 J for pulsed systems Class 4 Laser Classification correct answers -high power, hazardous to eye or skin from direct beam -may pose a diffuse reflection or fire hazard -pose ancillary hazards including laser-generated air contaminants and hazardous plasma radiation Laser components correct answers -pumping system -lasing medium -optical cavity Pumping System correct answers -source of power that excites the lasing medium in order to create photons for the laser beam -can be an electrical source, a flash lamp or another laser Lasing Medium correct answers -what determines the wavelength of the system -four types: solid state, gas, dye, and semiconductor
