Researchers from Singapore, China and Japan have unveiled what they believe to be the first high-power self-mode-locked ceramic laser. The team says its simple approach can be applied to other high-power lasers, particularly those emitting at wavelengths where mode-locking elements such as semiconductor saturable absorber mirrors (SESAMs) are not available.

The Air Force Office of Scientific Research is funding research at the University of Notre Dame to advance the knowledge of near-field aero-optic deviations and their effect on directed energy.
After a successful upgrade, the FLASH facility achieved a world premiere by generating flashes of laser light at the minuscule wavelength of 6.5 nanometres (nm), thereby breaking the world record of 13.5 nm it established one year ago. The facility now provides even better research opportunities for the second measuring period, which will begin on November 19, 2007.
A Princeton-led research team has created an easy-to-produce material from the stuff of computer chips that has the rare ability to bend light in the opposite direction from all naturally occurring materials. This startling property may contribute to significant advances in many areas, including high-speed communications, medical diagnostics and detection of terrorist threats.
As one of the world's leading sheetmetal and fabrication machinery manufacturers, Durma recognises the importance of adopting a high level of technology into its press brakes. Lazer Safe's press brake control, safety and guarding technology has provided a suitable solution to streamline and enhance the operation, functionality, safety, performance and productivity of Durma machines. To further enhance machine productivity and operator safety, Lazer Safe has developed a new guarding solution.
The first application of optical supercontinuum lasers in flow-cytometry was reported in a recent Nature publication by researchers at National Cancer Institute (NCI) of the US National Institute of Health. The experiments were conducted using Fianium's SC450 white light source based on an ultrafast high power fiber laser integrated with photonic crystal fiber.
SensorTran Inc., a developer of the world¡¦s most advanced distributed temperature sensing (DTS) technology, today announced PerfectVisionTM, a revolutionary technology that enables unprecedented temperature measurement accuracy and repeatability regardless of changes in optical fiber condition, simplifies set up of DTS systems, and also dramatically extends the life and usefulness of optical fiber in DTS deployments.
Last week¡¦s 7th International Congress of Nitride Semiconductors (ICNS-7) in Las Vegas, NV, USA saw reports of the latest progress in nonpolar laser diodes from the likes of University of California Santa Barbara and Japan¡¦s Rohm Co Ltd.
Those who are afraid of the dentist or suffering from life long dental issues caused by bad genetics or problems in the past, there’s hope. The new FDA approved, patented laser protocol for gum disease is now on the market for the first time in South Florida and readily available in Pompano Beach.
Curtiss-Wright Corporation announced today that Siemens Power Generation has begun utilizing its laser peening technology to improve the fatigue strength of titanium last row blades on certain of their advanced steam turbines. The last row blades extract energy from the steam to drive electrical generators. Although laser peening technology has been utilized for several years to strengthen critical titanium components in commercial and military turbine engines, this application represents its first production use in power generation steam turbines.
