Term
What are the components of a laser?
Definition
Lasing medium
Pumping system
Resonant optical cavity

TB MED 524
Term
What determines the laser color?
Definition
The lasing medium

TB MED 524
Term
What are the classes/subclasses of lasers?
Definition
1, 1M, 2, 2M, 3R, 3b and 4

TB Med 524
Term
what does the M designation indicate?
Definition
that the laser would be a higher class when the effects of magnifying optics are used.

TB Med 524
Term
what does the R designation indicate?
Definition
reduced requirements

TB med 524
Term
Which laser class is exempt from control measures and considered incapable of producing damaging radiation levels during operation?
Definition
Class 1

TB med 524
Term
Which class of laser is considered harmless because it only emits in the visible spectrum and causes the human aversion response (blinking).
Definition
Class 2

TB med 524
Term
Which class of laser may be hazardous for direct or specular reflections but is not a fire hazard?
Definition
Class 3

TB med 524
Term
Which laser class is a hazard to both eye and skin, may be a fire hazard and may be a source of laser generated air contaminants?
Definition
Class 4

TB med 524
Term
What are the three categories of laser exposure?
Definition
Intrabeam viewing
Specular reflection
Diffuse reflection

FM 8-50
Term
What category of laser exposure is the most hazardous and occurs when the laser is directly viewed by the source?
Definition
Intrabeam viewing

FM 8-50
Term
What category of laser exposure occurs when the laser is directed at a reflective object and the beam is viewed indirectly?
Definition
Specular reflection

FM 8-50
Term
What category of laser exposure, that is the least hazardous, occurs when the laser is directed at a rough surface and scattered back into the eye?
Definition
Diffuse reflection

FM 8-50
Term
What can cause laser energy concentration to become more dangerous and increase up to a million times?
Definition
magnifying optics

FM 8-50
Term
What is the definition of NOHD (nominal occular hazard distance)?
Definition
The minimum safe direct beam viewing distanc without the use of magnifying optics.

TM
Term
what is the definition of MPE (maximum permissable exposure)?
Definition
The maximum time one could be exposed to laser radiation without hazardous effects to the eye or skin.

TB med 524
Term
What are the three critical parts of the eye damaged by lasers?
Definition
Cornea
Retina
Fovea

FM 8-50
Term
what are the three categories of laser injury
Definition
Retinal
Corneal
Skin burns

FM 8-50
Term
What are the 7 factors that negatively affect laser designation operations?
Definition
Laser beam divergence and spot size
Atmospheric scatter
Reflections
Overspill/underspill
spot jitter
bore sight error
podium effect

FM 3-04.155
Term
What determines the spot size at a given distance?
Definition
Beam divergence

JP 3-09
Term
This occurs when the laser spot is larger than the inteded target and some of the energy goes beyond the target and impacts an object or terrain behind the intended target.
Definition
Overspill

FM 3-04.155
Term
This occurs when some of the laser energy impacts either terrain or an object short of the intended target.
Definition
Underspill

FM 3-04.155
Term
This is the result of motion of the designator.
Definition
Spot jitter

FM 3-04.155
Term
If the laser energy and the sighting mechanism of the designator are not matched up it will result in what?
Definition
Bore sight error

FM 3-04.155
Term
what is the definition of podium effect?
Definition
When the laser guided weapon cannot see the reflecting surface because it is out of view.

JP 3-09
Term
What is the NOHD for the laser pointer?
Definition
300m

TM
Term
What is the NOHD for the laser designator?
Definition
15km
