But if, for example, the absorption length is 300 cm then all optical photons will not travel 300 cm before being absorbed, the beam intensity will be 1/e after one absorption length. <br> <br> What I'm interested in is when in the calculations is the distance an optical photon travels determined. Is the distance sampled from a probability distribution before the actual transport begins? </div> <div><br> </div> <div>Best regards</div> <div>Jenny </div> <div><br> </div> <div><br> </div> <div><br> Skickat från min iPhone</div> <div><br> 7 jan 2013 kl. 20:00 skrev "Vesna Cuplov" <<a href="mailto:vesna.cuplov@gmail.com">vesna.cuplov@gmail.com</a>>:<br> <br> </div> <blockquote type="cite"> <div>Hello,<br> <br> The absorption length is the distance the optical photon travels before being absorbed by the medium bulk. <br> <br> vesna<br> <br> <div class="gmail_quote">On Mon, Jan 7, 2013 at 6:11 PM, Jenny Nilsson <span dir="ltr"> <<a href="mailto:jenny.nilsson@radfys.gu.se" target="_blank">jenny.nilsson@radfys.gu.se</a>></span> wrote:<br> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hello forum,<br> <br> I have a question regarding the absorption length used in the optical transport.<br> <br> Is the distance an optical photon travels in a medium sampled before the transport begins?
