Pulsed lasers allow for selective heating of specific targets, this is also known as? Answer- Selective Photothermolysis
The rate/amount of energy delivered within a given area is known as? Answer- Fluence
An increase in fluence equals an increase in what? Answer- Heat. Resulting in more
damage
The length of time the light/energy is in contact with the target that is measured in milliseconds (ms): Answer- Pulse width/Pulse duration
If the time of pulse duration is changed from milliseconds to nanoseconds the laser is what? Answer- Q Switched
A Q switched laser is used for what? Answer- Tattoo removal
Which skin types can tolerate an Alex laser? Answer- 1-4
Which skin types can tolerate a Nd:YAG laser? Answer- All skin types
Which skin type should only have electrolysis and no laser? Answer- Type 1
If the pulse width is greater than the thermal relaxation time it results in? Answer- A burn
If the pulse width is less than or equal to the thermal relaxation time it results in? Answer- Perfect hair removal
Larger structures have __________ thermal relaxation times (TRT) Answer- Longer
Smaller structures have _______ thermal relaxation times (TRT) Answer- Shorter What kind of pulse widths protect the epidermis, penetrate deeper and cool more slowly? Answer- Long
Longer pulse widths are for what skin type? Answer- 4-6
What kind of pulse widths are more aggressive and heat up and cool down quickly? Answer- Short
Shorter pulse widths are for what skin type? Answer- 1-3
