Pulsewidths, thermal relaxation times and ‘cooking’ times in photothermal treatments

Posted in Interesting stuff

After my previous post, several people asked me to explain more about pulsewidths and thermal relaxation times, and how they relate to each other.

The truth is, they are all unrelated!! They are intertwined, but not directly related. I thought it might be best to describe them using a bunch of graphs. So, I made a little video to explain them all.

I hope this makes sense to you all but feel free to contact me if you have more questions.

Hope this helps,

Mike.
