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 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
What is photothermal? - Answers Light energy transformed and dissipated as heat
What is photoacoustic? - Answers Energy delivered so fast a shock wave is created
