[ <a href="/nanop2018/" onclick="return showAbstract('1');">view full abstract</a> ] </p> </div> <div id="abstract_long_1" style="display:none;"> <p> <p>Photoacoustic imaging is a diagnostic technique which is based on the detection of acoustic waves induced in tissue by the absorption of electromagnetic radiation, usually from pulsed sources on a nanosecond timescale and with wavelengths between 600 and 900 nm.聽This technique can be used to detect microcalcifications in breast tissue and a wavelength between 600 and 800 nm is optimal for this particular case.In this work we present a scheme for an inexpensive and simple device that emits 9 nanosecond pulses over 1 mJ at a 710 nm wavelength which is based on an aperiodically poled ferroelectric crystal (Lithium Niobate, LiNbO<sub>3</sub>) pumped with a Nd:YAG pulsed laser source to obtain the red beam and is a viable source for biomedical applications like Photoacoustic imaging. The wavelength conversion from 1064 nm to 710 nm was achieved by two cascaded nonlinear optical processes within the Lithium Niobate crystal. First by optical parametric generation at degeneracy point a signal wave with 2128 nm wavelength is generated and simultaneously a sum-frequency generation process between the pump and signal waves results in the red beam.</p> </p> </div> <h2>Authors</h2> <ol> <li> <u>Juan Gonzalez</u> (Universidad Aut贸noma de Ciudad Ju谩rez) </li> <li> Liliana Martinez (Universidad Aut贸noma de Ciudad Ju谩rez) </li> <li> Roger Cudney (CICESE) </li> <li> Jose Enriquez (Universidad Aut贸noma de Ciudad Ju谩rez) </li> <li> Rurik Farias (Universidad Aut贸noma de Ciudad Ju谩rez) </li> <li> Eduardo Melendez (Universidad Aut贸noma de Ciudad Ju谩rez) </li> </ol> <h2>Topic Area</h2> <p> Optical sensing from solid state to bio-medicine </p> <h2>Session</h2> <p> PS2 » <a href="/nanop2018/delegates/session/47/" >Poster Session</a> (13:30 - Tuesday, 2nd October, HALL & ROOM 3) </p> <div class="presentation_files"> <h2>Presentation Files</h2> <p>The presenter has not uploaded any presentation files. </p> </div> </div> </div> </div> <div id="page_content_side_container"> <div class="page_content_side"> <div class="menu"> </div> </div> </div> <div class="clear"> </div> </div> <div id="page_footer"> <div id="page_footer_container"> <div class="links"> <a href="mailto:support@exordo.com" >Email Support</a> • <a href="https://www.exordo.com/blog/" onclick="window.open(this.href,'_blank');return false;">Blog</a> • <a href="https://www.exordo.com/legal/data-protection-and-privacy-policy" onclick="window.open(this.href,'_blank');return false;">Privacy Policy</a> • <a href="/nanop2018/cancellation-policy" >Cancellation Policy</a> </div> <div class="powered_by"> <div class="pb"> powered by </div> <div class="exordo"> <a href="http://www.exordo.com" onclick="window.open(this.href,'_blank');return false;"><img src="/nanop2018/img/template/exordo_logo.png" height="24" width="121" alt="Ex Ordo" /></a> </div> </div> </div> </div> </div> <div class="url" style="display: none; text-indent: -999em;">http://programme.exordo.com/nanop2018/system/is_sync/</div> <script type="text/javascript" src="/nanop2018/packages/starolas/js/is_syncing.js"></script> </body> </html>
