What is a laser? - correct answer✔✔A device that generates a beam of coherent light
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
What is photothermolysis? - correct answer✔✔A microsurgery technique used to target a
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
specific area. A process that turns laser light into heat. ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
Uses a specific wavelength and pulse duration
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
4 main components of a laser system? - correct answer✔✔Energy source
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
Laser medium ||\\//||
Optical resonator ||\\//||
Wave guide ||\\//||
2 differences of laser light - correct answer✔✔Spreading (non-coherent)
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
Single wavelength (coherent) ||\\//|| ||\\//||
, What is spot size? - correct answer✔✔The width of the beam measured in millimeters.
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
The spot size affects the penetration depth.
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
Larger= courser darker hair ||\\//|| ||\\//|| ||\\//||
Smaller = finer hair ||\\//|| ||\\//|| ||\\//||

||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
Uses Blue yellow and red light
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
Not suitable for darker skin tones
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
Describe ND:YAG laser - correct answer✔✔Suitable for most skin tones
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
Long pulse ||\\//||
Long term results
||\\//|| ||\\//||
Uses a carbon based lotion
||\\//|| ||\\//|| ||\\//|| ||\\//||
Can be less painful
||\\//|| ||\\//|| ||\\//||
What is a nanometer? - correct answer✔✔A spatial measurement
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
One times 10 to the power of 9
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
What wavelengths are measure in
||\\//|| ||\\//|| ||\\//|| ||\\//||
