Questions with Fully Detailed
Solutions
Daily Maintenance Duties - -Vacuum Vents, Wipe Calport, Wipe Down
Handpiece, Dust Box, Check Slider Window, Check Distilled Water Level,
Perform User Verification
-What is in section 6 of the manual? - -Fault Codes
-What does L.A.S.E.R. stand for? - -Light amplification by stimulated
emission of radiation
-What is an atom made of? - -Electrons, nuetrons, and protons
-What is a photon? - -Packet of light energy
-What is spontaneous emission? - -Resting stage by emitting a photon
-What is stimulated emission? - -Excited stage by emitting two photons
-A laser beam is generated by... - -Amplification
-Laser is light is... - -Non-ionizing
-What is ionizing radiation? - -Gamma rays, x-rays, nuclear radiation that
cause cell mutation
-What is the electromagnetic radiation wave of an Alexandrite laser? - -
755nm
-What is the electromagnetic radiation wave of a Nd:Yag laser? - -1064nm
-What is monochromatic? - -All one color
-What is coherent? - -All light waves are in the same phase and parallel
-What is collimated? - -All light waves are parallel
-What is polychromatic? - -Many colors white
-What is incoherent? - -Not the same direction
, -What is not collimated? - -Not intense
-What does the Nd:Yag laser target? - -The hemoglobin and melanin in the
hair follicle
-What does the Alexandrite laser target? - -Melanin like crazy
-What makes the IPL different than a laser? - -Doesn't get as much
absorption as laser and is polychromatic, incoherent, and non collimated

-How is a Q-switched laser different than an Alex or a Nd:Yag laser? - -It
delivers the energy in a nano second and is photoacoustic
-What is a nanometer? - -Measurement of light energy

absorption of light energy
-What is a chromophore? - -The target of light. Blood, melanin, and water
-What is phagocytosis? - -Physiological process by which the body absorbs
and eliminates the destroyed target
-What is selective photothermolysis? - -Laser light of a specific target
containing the adequate chromophore withe damaging the surrounding
tissue.
-What is thermal relaxation time? - -Time it takes for the tissue to cool down
and dissipate to surrounding skin
-What are the 4 basic laser parameters? - -Wavelength, pulse duration, spot
size, and fluence
-What is the pulse duration? - -Duration of each laser pulse
-What is the pulse duration of a 755nm laser? - -3ms
-What is the pulse duration of a 1064nm laser? - -Varies from 3ms to 20ms
-What do long pulses target? - -Thick hair
-What do short pulses target? - -Fine hair
