Corning believes that its new G-2000 green laser demonstrates the industry's highest commercially available performance in terms of optical power, efficiency and bandwidth. As a result, the company says that the laser is well suited to meet the demands of the growing market for portable microprojection devices.

By embedding a quantum dot within a semiconductor LED structure, researchers in the UK believe that they have created the first electrically driven source of entangled light. Although the most likely beneficiary is quantum computing, entangled light can also be used for quantum imaging, which improves resolution, and for secure communications using quantum cryptography (Nature 465 594).

The “One Shot” program originally aimed to give snipers the power to hit a target from 2000 meters away in winds as high as 40 miles per hour. In the first phases of the 3-year-old program, shooters used prototype rifles dressed with lasers and fancy computer hardware to do damage from 1,100 meters away in 18-mile-an-hour winds. The scope-mounted lasers can “see” wind turbulence in the path of the bullet and feed the data to computers, enabling real-time calculation of — and compensation for — the wind-blown trajectory.

The physics and laser show at Lund University will be taking to the stage at the World Expo in Shanghai. The European Commission has invited the physics researchers, who are now packing the three tons of equipment for the flight to China.
The popular physics and laser show in Lund has been performed just over 1 100 times for more than 220 000 people over the 15 years of its existence. Now it is going on a long-distance trip to the 2010 World Expo in Shanghai.

GOLETA, Calif.–BUSINESS WIRE–Kaai, Inc., a world leader in commercialization of green and blue laser diodes, announced shipments of its new blue laser diode product for display and specialty applications. The company will present a product introduction for the blue laser and an update on its green laser commercialization at Projection Summit 2010 in Las Vegas, Nevada on June 7, 2010.
Kaai’s new blue laser diode is designed for integration into portable applications such as embedded and companion pico projectors and features 60 mW of 445 nm single mode output power in a compact TO‐38 package. The lasers operate with high efficiency and require minimal power consumption over a broad temperature range, meeting the demanding requirements of consumer projection displays, defense pointers and illuminators, biomedical instrumentation and therapeutics, and industrial imaging applications. Kaai’s blue lasers are based on the company’s patented and proprietary InGaN semiconductor technology and are fabricated on innovative GaN substrates.
Kaai’s presentation at Projection Summit 2010 is entitled “The Emergence of Direct Emitting Green and Blue Semiconductor Lasers for Display Applications.” For additional information, see http://www.projectionsummit.com.

Airborne lasers have “stripped” away thick rain forests to reveal new images of an ancient Maya metropolis that's far bigger than anyone had thought.
An April 2009 flyover of the Maya city of Caracol used Light Detection and Ranging (LiDAR) equipment—which bounces laser beams off the ground—to help scientists construct a 3-D map of the settlement in western Belize. The survey revealed previously unknown buildings, roads, and other features in just four days,

A team of conservation experts today began a project to digitally record Mount Rushmore.
The team, from Historic Scotland and Glasgow School of Art, are using a laser scanner to capture in 3D the rock carvings of four US presidents in South Dakota.
They are firing the laser at the rockface millions of times a second. It bounces back and measures the distance to provide a precise record of the sculpture.
It is the first international site to be recorded as part of a project to create virtual models of 10 World Heritage sites.
