light in a form of wave
I.P.L - ✔✔Intense pulse laser
Ablative - ✔✔Vaporization, cutting, or removal of a portion of the epidermis and
dermis
Wave length - ✔✔A wave length is measured from the distance of the top wave to the
next
Amplitude - ✔✔The height, top to bottom
Chromophore - ✔✔The target in the epidermis and dermis the absorbs the laser beams

Coherent - ✔✔All of the light waves are traveling in the same direction and in unison
with each other (parade/military)
Nanometer - ✔✔A Billionth of a Meter (nm)
Micrometer - ✔✔A Millionth of a Meter (um)
Diode Laser - ✔✔Work on hair removal, vascular lesions. is photo-thermal. 800-980 nm
