I’ve just made a couple of little animations looking at the differences between the laser wavelengths we use for tattoo removal and how anisotropy comes into play.
You might be surprised at what actually happens in the skin.
Anisotropy is rarely discussed in the laser tattoo world, yet it has significant effects on treatment outcomes. Likewise, the different wavelengths have a range of positive and negative effects which we should all consider.
I started in medical lasers in 1986! I have been involved in clinical research, medical laser and IPL development, sales and marketing across Europe and South East Asia, business start-ups, theoretical research into laser-tissue interactions, training course development, writing articles for peer-reviewed journals and industry magazines plus I play bass guitar in a rock 'n' roll band too!!

Good one Mike! Question, how does pulse width effect this? Cheers, Chris

Not really. This is all to do with the optics, not the ‘thermals’. That’s another story!!
Scattering and anisotropy are purely optical phenomenon. The pulsewidth makes no difference, unless it is sufficiently long to change the physical structure, and hence the optical properties, of the medium.
