Lasers CST Exam
Light amplification by stimulated emission of radiation - answer laser
the laser light beam is ______________ (one color or one wave length) - answer
monochromic
all of the wave lengths are __________ (they wave together and are lined up) - answer
coherent
laser light will travel in the ________ direction and are _________ to each other -
answer same ; parallel
_______ can emit their light beam in brief spurts (pulsate), or they can produce
continuous light beams - answer lasers
an _________ __________ is needed to produce a laser beam, they can be gases,
solids, crystals, liquid, dyes and free electrons - answer active medium
you need an energy source for lasers; it may be ________ or __________ - answer
electrical or radiofrequency
lasers contain an _____________ system so the beam can change direction -
answeramplification
lasers contain a ________ guide to aim and control the beam (pulsing or continuous) -
answerwave
lasers emit a beam from __________ to ______________ - answerinvisible to infrared
lasers have ______ ______ to prevent the beam from going beyond its target. They
include: wet towels, sponges, titanium, or quartz rods - answerback stops
for this laser the medium used is argon gas - answerargon laser
for this laser it emits a blue-green beam - answerargon laser
for this type of laser the beam travels through clear tissue very well so it is commonly
used on the eye to vaporize bladder tumors - answerargon laser
the medium used in this laser is carbon dioxide gas - answerCO2 laser
