Sony, Sumitomo push laser projectors forward with a new, more powerful green laser diode
As cool as lasers are, so far there are precious few commercially available display devices available that use them. That may change with this new green semiconductor laser diode announced by Sony and Sumitomo, capable of the brightness necessary to replace the more expensive light sources used to fill in the middle of the RGB setup. According to the two companies, it's the world's first one capable of over 100mW power at 530nm, which they think will make it a fit for both advanced projectors and compact light projectors. Check after the break for more details on how the technology came to be -- drawing heavily on Sumitomo's production techniques and Sony's GaN laser technology developed with Blu-ray -- we'll let you know when there's a LaserVue or REDray setup priced for general consumption.
Microvision integrates direct green laser into pico projector prototype, completes RGB achievement
You should by now be aware that we're big fans of Microvision's Show WX pico projectors. Whether integrated into the smartphones or gaming peripherals of the future, we feel like the company's Laser Display Engine has a big part to play in our lives. It's therefore very welcome news to hear that its research team has managed to integrate a "direct" green laser into the portable projector setup, making for simpler and cheaper manufacturing of smaller components. Up to this point, Microvision has been performing its color mixing using a red laser, a blue laser, and a red laser specially re-calibrated to output green light, but that added bit of complexity can now be set aside with the inclusion of lasers that produce green hues natively. The company cites at least five global manufacturers ready to produce direct green beamers in commercial quantities by late 2011, so with a bit of luck and price competition, the pico projector dream might have itself a glorious realization after all.
Green laser for microprojectors developed, microraves soon to follow
Japanese company QD Laser has apparently developed a green laser which could up the ante in the HD pico projector market. The laser -- which is just 5.6mm in diameter and outputs a 532 nanometer, pure green light -- was shown off as a working prototype at CEATEC. QD says their green laser (the hardest type to make) will be well-suited to gadgets like cellphones and laptops because of its low power consumption and wide operating temperature. Mass production is seemingly planned for next year, with the hopes that each little laser will run $10, cheaper than the one currently available, which is manufactured by Corning. You know what we always say: rave on.
The Jasper Keynote RF green laser pointer: Powerpoint or Astronomy, you choose
If you've been waiting around for the world's first green laser with RF Powerpoint slide-control then today's your lucky day. Sure, sissies will get by with their weak sauce red laser pointers, but any self-respecting he-C-leveler knows that green lasers -- some 50 times stronger than red -- are where the real action is. In fact, Jasper say it's so strong that it's "ideal for astronomy use." See little Billy, right there... that's the cheese I was telling ya about. Ok, ok, we know how sky pointers work, but still. $169 with USB receiving device right in the box.
