ultrafast lasers News
Fiber vs. Disk: Which Laser Will Make the Cut?
Jul 1, 2011 — Some in the industry say they see fiber continuing to make large gains in the manufacturing space, but others say don’t count thin-disk out. The boom in fiber lasers that began several years ago has led some to question whether there is still room in the industrial manufacturing space for both the glamorous new star and its slightly less hip cousin, the disk laser. A short survey of companies on both sides – and neither side – of the issue reveals that the answer is yes,...
Lasers Generate Pure Microwave Signals
GAITHERSBURG, Md., June 28, 2011 — A new low-noise oscillator is generating microwave signals more pure and stable than those from conventional electronic sources. The apparatus could improve signal stability and resolution in radar, communications and navigation systems, and in...
Ultrafast free-space communications achieved with lasers
HOBOKEN, N.J. – A new high-speed communications technology that is not limited by a physical conductor, such as fiber optics, uses laser light to transmit data through readily available open space. This optical free-space technology could revolutionize...

PETALUMA, Calif., May 13, 2011 — Raydiance Inc., a developer of ultrafast laser technology, has announced that entrepreneur and software industry veteran Dick Pierce has been named chief executive officer. Pierce succeeds company founder Barry Schuler, who will continue as...
Expansion in Asia
May 1, 2011 — Based in Pessac, France, Amplitude Systemes has announced that it will open an office in Taipei, Taiwan, to provide sales and technical support to customers in the Asia-Pacific region. The company develops and manufactures diode-pumped ultrafast...
Imaging in the Ultrafast Lane
May 1, 2011 — For ultrafast imaging at wavelengths well below the visible, consider the work being done by a team led by professors Henry Kapteyn and Margaret Murnane. The married couple holds appointments in physics at the University of Colorado at Boulder and...
Ultrafast laser scribes solar cells
May 1, 2011 — A new manufacturing method using an ultrafast pulsing laser could make thin-film solar cell arrays a more efficient and less expensive means of power generation. The current method of connecting solar panels into arrays that generate usable...
Laser Tech to Improve Free Space Communications
HOBOKEN, N.J., April 13, 2011 — A high-speed communications technology not limited by a physical conductor such as fiber optics has been developed using laser light to transmit data through readily available open space. This optical free space communication could lead to faster...
Pulse Management in the Real World
Apr 1, 2011 — The minute details of high-energy ultrafast pulse production are complex, but the process comprises four basic steps. In the first step, a seed laser – generally a mode-locked laser – generates relatively low energy pulses of 500 fs....
Amplitude Systemes Opens Office in Taiwan
PESSAC, France, March 29, 2011 — Amplitude Systemes has announced that it will open an office in Taiwan to provide sales and technical support to customers in the Asia-Pacific region. The company has appointed Quentin Mocaer to provide support to its existing and future...
A new technique for terahertz radiation
BOULDER, Colo. – A new laser-based source of terahertz radiation that is more efficient and less prone to damage than similar systems could be useful for detecting trace gases or imaging weapons in security screening. Researchers at JILA, a joint institute of the...
JILA Upgrades Terahertz Source
GAITHERSBURG, Md., Jan. 24, 2011 — JILA researchers have developed a laser-based source of terahertz radiation that is unusually efficient and less prone to damage than similar systems. The technology might be useful in applications such as detecting trace gases or imaging weapons in...
2010 Prism Awards for Photonics Innovation: The Finalists
Jan 1, 2011 — The finalists have been announced for the 2010 Prism Awards for Photonics Innovation, an international competition sponsored by Photonics Media and SPIE to recognize photonic products that test conventional ideas, solve problems and improve life...
JPSA Expands Job Shop, Apps Lab
MANCHESTER, N.H., Dec. 28, 2010 — JP Sercel Associates Inc. (JPSA) has expanded its job shop operations with the addition of new diode-pumped solid-state, ultrafast and excimer laser workstations. With the expansion of its job shop operations, JPSA can now accommodate its...

High-Average-Power Cryogenic Lasers for New Applications
Nov 1, 2010 — The fundamental metrics used to determine effectiveness for military applications are size, weight, efficiency, reliability, performance and cost. In the commercial world, size and weight are less important but nevertheless desirable to decrease...
’Molecular Fingerprinting’ Improved for Gas Detection
GAITHERSBERG, Md., Oct. 21, 2010 — Scientists have demonstrated a laser-based “molecular fingerprinting” technique that can differentiate billions of hydrogen-containing and other molecules from one another in gas in just 30 seconds or less — a performance that is...
‘Quantum Cats’ Made of Light
GAITHERSBURG, Md., Sept. 8, 2010 — "Quantum cats" made of photons have been created at the National Institute of Standards and Technology (NIST), boosting prospects for manipulating light in new ways to enhance precision measurements as well as computing and communications based on...
Shocking Results from DACs
LIVERMORE, Calif., July 14, 2010 — Lawrence Livermore National Laboratory (LLNL) physicists are using an ultrafast laser-based technique they dubbed “nanoshocks” to study shock behavior in tiny samples such as thin films or other systems with microscopic dimensions (a few...
The Ti:Sapphire Laser
Jul 1, 2010 — Since their invention in the early 1980s, titanium-doped sapphire (Ti:Al2O3 or Ti:sapphire) lasers and amplifiers have enabled countless applications in fundamental research in physics, biology and chemistry. Today, they play an important role...
Laser Device Produces Dark Pulses
GAITHERSBURG, Md., June 10, 2010 — Researchers have demonstrated a new type of pulsed laser that excels at not producing light. The new device generates sustained streams of "dark pulses" – repeated dips in light intensity – which is the opposite of the bright bursts in a...
