EXAM: Laser Safety Officer (AF)|133 Questions
with Verified Solutions

Class 1 Laser Classification Correct Answer-- 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 Answer--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 Answer--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 Answer--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 Answer--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 Answer--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 Answer--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 Answer--pumping system


-lasing medium


-optical cavity




Pumping System Correct Answer--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 Answer--what determines the wavelength of the system


-four types: solid state, gas, dye, and semiconductor




Optical Cavity Correct Answer--contains the lasing medium and reflective mirrors that

guide the laser beam


-provide amplification to create the desired laser parameters




LASER acronym Correct Answer-Light

Amplification by


Stimulated


Emission of


Radiation




Beam Characteristics Correct Answer--monochromatic


-coherent


-collimated




Monochromatic Correct Answer--light emitted by a laser is almost pure in color of a single

wavelength




Coherent Correct Answer--measure of the degree of phase correlation that exists in the

radiation field of a light source at different locations and different times


-waves are tightly in phase or in step with one another
