Q1 QUESTION 1 OF 79
L.A.S.E.R.
CORRECT ANSWER
Light Amplification of Stimulated Emission of Radiation
RATIONALE
This acronym defines the physical principle by which a laser generates a monochromatic, coherent beam of light through the
process of stimulated emission within an active medium. The key concept tested is the understanding of the fundamental
physical mechanism underlying laser operation.
Q2 QUESTION 2 OF 79
3 characteristics of a laser beam
CORRECT ANSWER
monochromatic, coherent, collimated
RATIONALE
Lasers produce light that is monochromatic (single wavelength), coherent (waves in phase), and collimated (narrow, low
divergence), differentiating them from conventional light sources. This unique combination of properties enables their
diverse applications in fields such as medicine and telecommunications.
Q3 QUESTION 3 OF 79
monochromatic
CORRECT ANSWER
single wavelength
RATIONALE
Monochromatic light consists of electromagnetic radiation of a single wavelength, which is its defining characteristic. This
concept is fundamental to understanding the behavior of light in optical phenomena.
Q4 QUESTION 4 OF 79
coherent
Page 2
, CORRECT ANSWER
waves of laser light tightly in phase with each other
RATIONALE
Coherent light consists of electromagnetic waves that are in phase, meaning their crests and troughs align, which is
characteristic of laser light due to its stimulated emission process. This temporal and spatial alignment of waves is the
defining principle of coherence.
Q5 QUESTION 5 OF 79
collimated
CORRECT ANSWER
light beams travel in parallel paths with minimum divergence
RATIONALE
Collimated light beams are those that travel in parallel paths, exhibiting minimal divergence, which is achieved by focusing
the light source at infinity or using a lens system. This principle is key in applications requiring a uniform and directed light
source, such as lasers and telescopes.
Q6 QUESTION 6 OF 79
what components does a laser consist of
CORRECT ANSWER
pumping system, optical cavity, laser medium
RATIONALE
A laser requires a pumping system to excite atoms, a laser medium where stimulated emission occurs, and an optical cavity
to amplify the light through feedback. This tripartite structure is foundational to laser operation.
Q7 QUESTION 7 OF 79
pumping system
CORRECT ANSWER
source of the power that imparts energy to the atoms of the lasing medium to create photons
RATIONALE
The pumping system provides the energy input necessary to excite the atoms within the lasing medium to higher energy
states, enabling stimulated emission of photons. This energy transfer is the fundamental mechanism by which a laser
operates.
