CTX Virtual Technologies, Inc, a technology company that manufactures and distributes mobile telecommunication, virtual imaging, touch screens and tablets, announces the completion of the world's first virtual keyboard using green laser.
CTX has developed what it is calling the world's first true green virtual laser keyboard in an extremely small form factor the size of a matchbox allowing over 2 hours of continuous usage per charge.
CTX has successfully developed the next generation true green laser diodes. Green laser diodes have until now been generated by converting the wavelength of infrared laser light from a light source using optical materials, but the light source is large and expensive. In addition, the conventional green lasers have difficulties achieving sufficient luminosity as their performance is limited to low output power. By introducing new techniques and improving the entire semiconductor laser production process, including structural design, crystal growth, wafer processing, and electrode configuration. CTX has been able to successfully develop true green semiconductor laser with an optical output power of more than 50 milliwatts at a wavelength of 520 nanometers.
This true green semiconductor laser diode is highly reliable, the company reports, and up to 3 times brighter than the currently utilized red keyboard projections. CTX has successfully packaged and created specialized diffractive optics to work with this new diode and will display the first prototypes at the Consumer Electronics Show 2014 in January in Las Vegas, Nevada (US) with consumer production expected to start in the first quarter of 2014.
