measured in milliseconds?
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: Fitzpatrick 1-4
