Gaussian beam News
Coherently Combined, 10.4-kW Laser Delivers Record Power
WASHINGTON, D.C., Oct. 19, 2020 — Coherent beam combining, paired with direct water cooling in the testing stage of development, has helped produce the new ultrafast fiber laser technology introduced by the Institute of Applied Physics (IAP) at Friedrich Schiller University Jena...
Lasers: A Unique Microscopy Source
Nov 2, 2018 — The optical microscope dates back to the time of Galileo. For most of the past century, microscopy was widely regarded as a ubiquitous and extremely mature field. Today, the picture is very different. Optical microscopy is an incredibly dynamic...
Airy Beam Light-Sheet Microscopy Holds Promise for Life Sciences Imaging
May 24, 2016 — Airy light-sheet microscopy has great potential to help further research and clinical diagnoses through its ability to image larger 3D volumes of tissues and organoids. Developed in the last three years, it is best-suited to the fields of...
Nano light mill motor controlled by wavelength changes
BERKELEY, Calif. – A newly developed light mill could lead to a whole new crop of nanoscale devices, including nanoscale solar light harvesters, nanoelectromechanical systems, and nanobots that could manipulate DNA and other biological molecules in vivo. ...
Nano-Sized Light Mill Drives Microdisk
BERKELEY, Calif., July 8, 2010 — Researchers have created the first nano-sized light mill motor whose rotational speed and direction can be controlled by tuning the frequency of the incident light waves. STM image shows a gammadion gold light mill nanomotor embedded in a 300...
Lasers reinforce lightweight structures
PARIS and AACHEN, Germany – At the JEC Composites Show in Paris, researchers from Germany’s Fraunhofer institutes showed how lasers can make the manufacturing of fiber-reinforced thermoplastic structures more efficient, reliable and automated. Fiber-reinforced plastics...
Ultrashort-Pulse Amplifier
Aug 1, 2009 — EdgeWave GmbH has released the Innoslab ultrashort-pulse IS10I-A amplifier with an average power of 100 W. The device features a circular Gaussian beam with M2 <1.5, a line-shaped one-dimensional Top-Hat with M2 <2 and square two-dimensional...
Diamond Heat Spreader Facilitates VECSEL’s Room-Temperature Operation
May 1, 2006 — The circular Gaussian beam of a vertical-external-cavity surface-emitting laser (VECSEL) is more useful in numerous applications than the elliptical, nonsymmetrical beam emitted by edge-emitting lasers. The external-cavity design — with the output...
External Cavity Controls Transverse Mode in VCSEL
Aug 1, 2003 — The fundamental transverse mode of a vertical-cavity surface-emitting laser (VCSEL) produces a high-quality Gaussian beam, as it does with any laser. As the bias current of the device is increased, however, higher-order transverse modes often begin...
Point Source
Jan 1, 2003 — The iFlex-2000 combines 405-nm laser diode technology with single-mode polarization-maintaining fiber to produce a pure Gaussian beam for high-resolution imaging applications. Many applications at this wavelength have been cost-prohibitive and...
