QPC, a world leader in the development and commercialization of high brightness, high power semiconductor lasers for the industrial, defense, and medical markets, today announced that it has demonstrated a green laser based on QPC's proprietary BrightLase semiconductor laser technology. The QPC green laser is designed for potential display applications including mobile phone projectors, rear projection televisions, and cockpit displays, all of which require high speed direct modulation, low power consumption, and low cost in high volume production.
"This successful demonstration expands our BrightLase technology to include visible colors and opens up significant potential new markets and product applications for us," said QPC Chief Executive Officer Dr. Jeffrey Ungar. "We believe that high efficiency, compact visible lasers with low production cost could enable us to become a strong competitor in these new markets, and we will remain diligently focused on our development efforts as we continue to execute our growth plan," Dr. Ungar concluded.
QPC's green laser design may be modified in the future to generate other visible colors such as red and blue which, together with the green, are required to replace the expensive, short lived, and inefficient lamps that are common engines in conventional display technology.
The green laser demonstration is based on frequency doubling of QPC's proprietary BrightLase single-mode laser technology announced earlier this year. BrightLaseR single-mode lasers produce single frequency output powers exceeding 3 Watts continuous wave and peak conversion efficiencies greater than 50% at 1064 nm. For high reliability, these products are assembled using state-of-the-art hard-solder processes and thermally expansion-matched mounts.
