LATEST: Laser Safety Officer – BEO Test Questions
and Answers 100% Pass
Radiant Energy (Q) Correct Answer-Energy that is emitted, transferred or received.
Measured in Joules (J)
Radiant Power Correct Answer-Power emitted, transferred, or received in the form of
radiation. Measured in Watts (W)
Irradiance (E) Correct Answer-(Power Density) Radiant power striking a surface divided by
the surface area W/cm2
Radiant Exposure (H) Correct Answer-(Energy Density) Energy striking a surface divided by
the surface area exposed J/cm2
What does Laser stand for? Correct Answer-Light Amplification by Stimulated Emission of
Radiation
What does a laser consist of? Correct Answer-A Pumping System - Source of the power
that imparts energy to the atoms of the lasing medium to create photons

and Answers 100% Pass
An Optical Cavity - Contains the medium, has mirrors and provides amplification/selection of
photons
Laser medium - Can be solid state matrix(ND:YAG), gaseous (HeNe 632.8nm red, CO2, Ar,Kr),
dye lasers (Rhodamine 6G), and semiconductor (Gallium Arsenide diode )
What are the two modes of laser operation? Correct Answer-Continuous Wave - Stable
beam power over 0.25s
Pulsed -
Single Pulsed/Repetitively pulsed - Pulsed repetitively per second (Hz)
Q-switched - stored PE to increase power before release
Mode Lock - Modulating standing waves of slightly different wavelengths combine to produce
short pulses
What are three characteristics of a laser beam Correct Answer-Monochromatic - Single
wavelength
Coherent - Waves of laser light tightly in phase with each other
Collimated - Highly focused

What are the three main US Government agencies involved in laser regulation? Correct
Answer-OSHA, Federal Aviation Administration (FAA) and FDA
What AFI covers the Laser Radiation protection program Correct Answer-AFI 48-139
(minimum requirement for RPP) and DoD Instruction 6055.15, we also use ANSI
136.1(commercial)
What constitutes a class 1 laser? Correct Answer-Cannot emit laser radiation capable of
causing eye/skin injury.
A 1M is similar, but can cause damage if passed through magnifying optics.
These may be a higher class during maintenance/service
What constitutes a class 2 laser? Correct Answer-2 - Staring into beam is an eye hazard.
CW max 1mW
2M - Potentially hazardous if collecting optics are used;
CW max 500mW
