Figure 66 - If we target chromophores with high absorption coefficients, the local temperatures will also increase – linearly
The absorption coefficient of any tissue or cell determines how much light it will absorb. Cells with low coefficients will absorb quite poorly, resulting in low temperature rises (Figure 66). Conversely, any target with high absorption coefficients will rise in temperature much more, for the same incident fluence. This is also simple!
What happens with different pulsewidths?
Figure 67 - If we increase the pulsewidth, the local temperatures will also increase – with continuous lasers
