Control could make random lasers useful
VIENNA – Random lasers, with their very irregular angular emission pattern, are difficult to tune. But a team at Vienna University of Technology has theoretically shown that random lasers can be controlled by actively shaping the spatial pump distribution,...
Controlling Random Lasers
VIENNA, July 15, 2013 — Random lasers, with their very irregular angular emission pattern, are difficult to tune. But a team at Vienna University of Technology has theoretically shown that they can be controlled by actively shaping the spatial pump distribution, giving...
Quantum dot ink will make lasers printable
CLAYTON SOUTH and MELBOURNE, Australia, & PADUA, Italy – Printing techniques that already have been incorporated into solar cell manufacturing could prove useful for the production of lasers and other emitting optoelectronic devices, according to researchers from Australia and Italy. Quantum dots are...
Coherent Signs Licensing Agreement With Osram GmbH
Dec 21, 2006 — Laser maker Coherent Inc. of Santa Clara, Calif., announced it has signed a licensing agreement with Germany-based lighting manufacturer Osram GmbH for the use of Coherent's optically pumped semiconductor lasers in consumer laser-based projection...
Multiwatt VECSEL Output Is Wavelength-Tunable
Mar 1, 2006 — Optically pumped, vertical-external-cavity surface-emitting lasers (VECSELs) produce multiwatt outputs with good beam quality, but until now their spectral characteristics have been less than optimal. Their linewidths are too wide for many...
Group to Develop Platform for Free-Space Communications
Feb 1, 2004 — A group of UK companies and universities will develop a next-generation optical platform for free-space optical communications. The proj-ect, known as Alfonso -- Adaptive Long-Wave Free-Space Optical Network Solutions -- and valued at more than...
