Laser Tattoo Removal – wavelengths and anisotropy

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.

How do the laser wavelengths compare in the skin?

What is ‘anisotropy’ and why does it matter?

All of the above is in Chapter 2 of our eBook – Laser Tattoo Removal.

Hope this adds to your knowledge,

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

    1. Hi 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.
