Photonic Products is showcasing its exciting new range of tiny laser diode collimators at LASER 2009 in Munich.
The new range of laser diode collimators achieves the technically difficult feat of combining high alignment accuracy with a tiny package at a competitive price. The range comprises a micro laser diode collimator which measures just 4.5mm in [...]
Sanyo Electric Co Ltd of Japan has developed a blue-violet laser diode with a pulse oscillation output power of 450mW (Fig 1). The emission wavelength is 405nm, designed to make it possible for Blu-ray Disc drives to record 4-layer discs at 12x speed. A 4-layer disc would have a storage capacity of 100 Gbytes, enough [...]
Pb-Free Laser suits high-power RGB white light sources.
Designed as single longitudinal mode semiconductor laser diode with TE mode oscillation, Opnext HL6385DG offers 150 mW optical output power at 642 nm wavelength.
Aspect ratio of less than 2:1, coupled with 3 x 1 µm emitting chip size, allows efficient combination of multiple diodes in high-power RGB white [...]
A new fiber-optic laser system can measure wind speed and direction up to 1000 meters in front of a wind turbine, giving the massive machines enough precious seconds to proactively adapt to gusts and sudden changes in wind direction. The device, developed by Catch the Wind, a startup based in Manassas, VA, could improve the [...]
The most famous weapon of science fiction is rapidly becoming fact.
Like so much else in science fiction, the ray gun was invented by H.G. Wells. In the tentacles of Wells’s Martians it was a weapon as unanswerable by earthlings as the Maxim gun in the hands of British troops was unanswerable by Africans.
Science fiction, though, [...]
