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: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

Im Focus: Explanation for puzzling quantum oscillations has been found

So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics

Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a...

Im Focus: Dozens of binaries from Milky Way's globular clusters could be detectable by LISA

Next-generation gravitational wave detector in space will complement LIGO on Earth

The historic first detection of gravitational waves from colliding black holes far outside our galaxy opened a new window to understanding the universe. A...

Im Focus: Entangled atoms shine in unison

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...

Im Focus: Computer-Designed Customized Regenerative Heart Valves

Cardiovascular tissue engineering aims to treat heart disease with prostheses that grow and regenerate. Now, researchers from the University of Zurich, the Technical University Eindhoven and the Charité Berlin have successfully implanted regenerative heart valves, designed with the aid of computer simulations, into sheep for the first time.

Producing living tissue or organs based on human cells is one of the main research fields in regenerative medicine. Tissue engineering, which involves growing...
