Multi-segment all-fiber laser device

14.11.2012
<strong>Background</strong><br>

The compactness, ruggedness, high beam quality, and efficiency of fiber lasers make them attractive devices for applications in signal processing, optical communications and sensing as well as in medicine and industry. <br><br> <strong>Technology</strong><br> This multi-segment all-fiber laser includes active fiber laser segments, a first grating and a second grating as well as a coupling fiber segment arranged between the first and the second grating. The coupling fiber segment enables the coupling of gain and phase between the two gratings with the gain and/or phase being controllable. Preferably, the first and the second grating are distributed feed-back (DFB) grating structures. This all-fiber laser emits well-defined optical pulses and/or pulse trains of well-defined but adjustable wavelength.<br><br> <strong>Benefits</strong><br>

<ul> <li>Tunable pulse repetition rates </li> <li>First mode: stable train of optical pulses</li> <li>Second mode: two pulse trains with stable phase relations</li> <li>Tunable frequency difference between the two pulse trains</li> <li>Repetition rates between 100 Hz and 200 GHz, even up to 10 THz</li> <li>Operation wavelengths of both DFB lasers can be tuned relative to each other </li> </ul> <br> <strong>IP Rights</strong><br> US patent application (04/2009)<br> European patent application <br><br> <strong>Origin</strong><br> Humboldt-Universität zu Berlin</p>

Im Focus: Viaducts with wind turbines, the new renewable energy source

Wind turbines could be installed under some of the biggest bridges on the road network to produce electricity. So it is confirmed by calculations carried out by a European researchers team, that have taken a viaduct in the Canary Islands as a reference. This concept could be applied in heavily built-up territories or natural areas with new constructions limitations.

The Juncal Viaduct, in Gran Canaria, has served as a reference for Spanish and British researchers to verify that the wind blowing between the pillars on this...
