Here are the answers to yesterday’s tattoo removal quiz for our Austin patients:
(1) Blue and Green are the two most difficult colors of tattoo ink to treat.
(2) Q-switching is a technique by which a laser can be made to produce a pulsed output beam. The technique allows the production of light pulses with extremely high peak power, much higher than would be produced by the same laser if it were operating in a continuous wave mode. The tattoo removal lasers used in our Austin tattoo removal clinic operate in a nanosecond (billionth of a second) range.
(3) The ruby laser came first – it was first operated in 1960. The carbon dioxide laser was first used in 1964.
(4) Nd:YAG stands for Neodymium-doped yttrium aluminium garnet. This crystal is used as the lasing medium for solid-state lasers (including tattoo removal lasers).
(5) If a 1064nm wavelength is “frequency-doubled), a 532nm wavelength will result. Frequently is inversely related to wavelength, so a doubled frequency would be 50% of wavelength (so 1064 to 532 vs. 1064 to 2128nm).
Thanks for those of you who participated in our Austin tattoo removal quiz.
