The pulse is 50 fs at an intensity of 10^16 W/cm^2, the titanium foil is 100 nm. I would like to define the optical absorption in the foil myself with a simple absorption model like the exponential decay according to the Beer-Lambert law for example: I=I0*exp(-alpha*x), where we know the the absorption co-efficient alpha, and x is the distance into the target, and I0 is the intensity at the surface.</span></font></div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);"><font color="#000000"><span style="caret-color: rgb(255, 255, 255);"><br></span></font></div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);"><font color="#000000">This question has probably arisen before, so I would like ask the community for any experience or tools in implementing short pulse laser-solid heating.</font></div></div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);"><font color="#000000"><br></font></div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">Thanks in advance!</div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">Gareth</div></body></html>
