Ultraintense Laser Blast Creates True 'Black Metal'
Nov. 27, 2006 -- A process involving an incredibly intense burst of laser light that can change the properties of almost any metal to render it black could potentially make everything from fuel cells to a space telescope's detectors more efficient, said the scientists who inadvertently discovered it. "We wanted to see what would happen to a metal's properties under different laser conditions, and we stumbled on this way to completely alter the reflective properties of metals," said Chunlei Guo, assistant...
Micreon Fits Camel Through Needle's Eye
HANOVER, Germany, April 14, 2006 -- A German company that uses femtosecond lasers to make ultraprecise components demonstrated its technique last year by creating a pair of eyeglasses for a housefly. Micreon GmbH recently unveiled its latest creation to promote the technology: a tiny...
Laser Plasma Channels Power Paper Airplane
Feb 1, 2006 — A research team at the Institute of Physics of the Chinese Academy of Sciences in Beijing has used self-guided plasma channels created in air by a femtosecond laser to propel a 1.32-g paper airplane along an air-cushion track. The work, which the...

Jul 15, 2005 — Axsys Technologies Inc., a Rocky Hill, Conn., supplier of precision optical systems for applications in the aerospace, defense and high-performance commercial markets, announced it has received a $6.9 million order to manufacture thermal camera...
A Snip in Time May Save Lives: Laser-Cut Nerves Regenerate
Jan 1, 2005 — Scientists at Stanford University in California, the University of California, Santa Cruz, and the University of Texas at Austin have demonstrated a femtosecond laser technique with potential in nerve regeneration research. In a study published...
Advances Lead to Miniature Supercontinuum Sources
Oct 1, 2004 — Supercontinuum sources are finding increasing use in applications that require a source with very broad spectral bandwidth and high spatial brightness. A common method of generating supercontinuum light has involved the coupling of the output from a...
Femtosecond Lasers Fabricate Improved Optical Waveguides
Oct 1, 2004 — Many laboratories around the world are investigating the use of femtosecond lasers for fabricating optical waveguides. Recently, scientists in a US laboratory employed femtosecond lasers to create waveguides in poly(methyl methacrylate) (PMMA),...
Femtosecond Lasers Carve out a Niche in Micromachining
Jun 1, 2004 — The drive for miniaturization in electronics, photonics and biomedical devices is spurring an ever-growing need for laser micromachining. Femtosecond laser pulses provide unique capabilities for producing features as small as a few tens of...
Nd-Doped Fiber Laser Generates 360-fs Pulses at 900 nm
Jun 1, 2004 — Femtosecond lasers are useful in machining applications as well as in medicine, precise rangefinding and fluorescence studies. Fiber lasers offer an attractive alternative to conventional femtosecond sources because of their high efficiency and...
Femtosecond Laser Facility Planned for Canada
May 1, 2004 — The Canada Foundation for Innovation in Ottawa has announced the allocation of almost C$21 million for construction of the Advanced Laser Light Source. The facility, which will be located in Varennes and administered by the Université du...
Femtosecond Laser Probes Plasma Formation
Apr 1, 2003 — Pump-probe experiments employing femtosecond lasers have exposed the dynamics of numerous ultrafast phenomena. Researchers at Univer-sité Claude Bernard Lyon 1 in Villeurbanne, France, and the US Army Research Laboratory in Adelphi, Md., have...
