Using air to deflect lasers
Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original quality of the beam, reports an interdisciplinary.....»»

Giant Lasers Simulate Exoplanet Cores, Prove They"re More Likely to Have Life
Slashdot reader vikingo9 writes, "By smashing a piece of iron to insanely high pressures, using a laser the size of a football stadium, a team of scientists led by Lawrence Livermore National Laboratory have discovered that exoplanets 4-6 times large.....»»
FedEx Asks FAA To Let It Install Anti-Missile Lasers On Its Cargo Planes
With the right military equipment, a single person can target a plane from three miles away using a heat-seeking missile. While such a nightmare is a rare occurrence, FedEx has applied to the FAA seeking approval to install a laser-based, anti-missil.....»»
Researchers propose multi-aperture vertical cavity surface emitting lasers of varying size and shape
Vertical cavity surface emitting lasers (VCSELs) present the basis for large data rate optical interconnects in data centers. Presently VCSELs have replaced edge-emitting lasers for distances below 500 m due to their advantages such as on-wafer test.....»»
Exploring the hyperchaos of mid-infrared lasers
Chaos, often popularized as the 'butterfly effect', describes the irregular phenomenon of deterministic systems. Based on the unique features of sensitivity to initial conditions and unpredictability of future evolutions, chaos from laser diodes has.....»»
New System Would Let Us Know If Aliens Are Using Lasers to Communicate
It's conceivable that extraterrestrial intelligences are using powerful lasers to grab our attention, but we lack the proper tools to notice. A newly deployed system might be exactly what's needed for us to finally make contact. From a report: Two la.....»»
