Laser Hair Removal training Exam Questions with correct
Answers
what does the word LASER stand for? - light amplification stimulated emission of
radiation
/.what are the four characteristics of a wave? - wavelength, frequency, velocity,
amplitude
/.wavelength - distance between 2 peaks of the wave measured in nanometers
/.frequency - number of wave cycles per second; measured in hertz
/.velocity - speed of light
/.amplitude - height of the wave
/.what is the common standard of measure used for a wavelength? - nanometers
/.explain the correlation between the wavelength, energy, frequency, amplitude, and
penetration to the surface - -shorter waves have more energy, higher frequency, higher
amplitudes, less penetration
-long waves have less energy, less frequency, less amplitudes, more penetration
/.what is the range for visible light? (nm) - 400-780nm
/.what are actinic rays? - damaging rays that come from the sun
/.what wavelengths are considered to be actinic? - 0-400nm
/.what wavelengths for IR light? - 780-10,000
/.what is spontaneous emission? - process of energy absorption by electrons and
emitting spontaneously
/.what are the components of laser? - active medium, excitation mechanism, feedback
mirrors, laser output
/.what are 3 unique characteristics of the laser light? - 1) monochromatic
2) coherant
3) collimated
/.coherence - wave patterns are locked in one phase (up and down together)
, /.collimation - laser that creates a light beam that stays together as a tight beam of light
over long distance without diverging
/.monochromaticity - -one wavelength/color,
-same wavelength number, color
/.who were 3 people developing the theory of LASER? - -albert einstein
-charlers townes
-arthur shawlow
/.who invented the first laser and when? - -theodore maiman
-1960
/.in the visible spectrum, what is the color? - wavelength
/.give the order of colors in the visible spectrum - violet, indigo, blue, green, yellow,
orange, red
/.what is active medium of a laser? - substance that creates the laser light
/.what types of active medium are commonly used? - solid, liquid, gas, electronic
/.what is the energy source of a LASER? - stimulates active medium
/.types of the energy sources used in different lasers - direct current, radio frequency,
optical (flashlight), other lasers
/.what conditions do we use lasers in esthetics for? - -hair reducation
-hyperpigmentation
-skin rejuvenation
-spider veins
-stretch marks
-telangiectasia
-capillaries
-melasma
-tattoo removal
-acne
-laser lipo
/.what is the definition of chromophore? - substance that absorbs the laser light
/.what chromophore do we target in hair reduction? - melanin
/.what chromophore do we target in capillaries? - oxyhemoglobin
/.what chromophore do we target in hyper pigmentation? - melanin
