What does the Nd:Yag laser target? - Answers✔The hemoglobin and melanin in the hair follicle
What does the Alexandrite laser target? - Answers✔Melanin like crazy
What makes the IPL different than a laser? - Answers✔Doesn't get as much absorption as laser
and is polychromatic, incoherent, and non collimated
What is a tattoo removal laser? - Answers✔Q-switched laser
How is a Q-switched laser different than an Alex or a Nd:Yag laser? - Answers✔It delivers the
energy in a nano second and is photoacoustic
What is a nanometer? - Answers✔Measurement of light energy
What is photothermolysis? - Answers✔Destruction of a target by selective absorption of light
energy
What is a chromophore? - Answers✔The target of light. Blood, melanin, and water
What is phagocytosis? - Answers✔Physiological process by which the body absorbs and
eliminates the destroyed target
What is selective photothermolysis? - Answers✔Laser light of a specific target containing the
adequate chromophore withe damaging the surrounding tissue.
What is thermal relaxation time? - Answers✔Time it takes for the tissue to cool down and
dissipate to surrounding skin
What are the 4 basic laser parameters? - Answers✔Wavelength, pulse duration, spot size, and
fluence
What is the pulse duration? - Answers✔Duration of each laser pulse
What is the pulse duration of a 755nm laser? - Answers✔3ms
What is the pulse duration of a 1064nm laser? - Answers✔Varies from 3ms to 20ms
What do long pulses target? - Answers✔Thick hair
What do short pulses target? - Answers✔Fine hair
What is the significance of a larger spot size? - Answers✔The energy is delivered and absorbed
at a deeper level
What is the significance of a smaller spot size? - Answers✔Has more energy but is scattered
What spot size has more energy? - Answers✔Small spot size
What is fluence? - Answers✔Rate of energy delivered to area
