LASER HAIR REMOVAL EXAM
QUESTIONS WITH CORRECT
DETAILED ANSWERS GRADED A+
Maximum permissible exposure - Answer-The level of laser to which a person may be
exposed without hazardous ocular or tissue effects.
nominal hazard zone - Answer-The zone in which direct, reflected, or scattered
radiation, during normal operation, exceeds the maximum permissible exposure.
components of light - Answer-wavelength, amplitude, frequency
Laser light is - Answer-monochromatic, collimated, coherent
ordinary light is - Answer-polychromatic, non-collimated, and the light diverges
active medium - Answer-the source of atoms that undergo excitation in a laser; can be a
solid, liquid, or gas
excitation mechanism - Answer--energy source that excites the active medium
-the energy source of the laser
feedback mechanism - Answer--laser power mirrors- mirrors positioned at each end of
the tasing medium that reflect light back and forth into the active medium increasing its
strength and amplifying the light into a powerful laser beam
output coupler - Answer--the front, partially transmissive mirror
- transparent mirror that allows the beam to leave the intracavity
YAG laser - Answer-emits infrared light at 1,064 nm: used for permanent hair reduction
and treatment for some vascular lesions
Alexandrite laser - Answer-755nm permanent hair reduction, and benign pigmented
lesions
Pulsed Dye laser - Answer-Is commonly used to treat vascular and pigmented lesions.
visible light at 595nm
Diode - Answer-810-940nm
power density - Answer-the amount of power distributed within the area of the spot
