Researchers have created the tiniest laser since its invention nearly 50 years ago, paving the way for a host of innovations, including superfast computers that use light instead of electrons to process information, advanced sensors and imaging.

New Smart Laser Countour Tracking Technology… Pretty cool.

Light sources using lasers for display applications, such as laser TV’s and pocket laser projectors, are expected to have superior properties in terms of size, weight and power consumption. For this reason, R&D activities aimed at commercialization of these devices have expanded rapidly over the past several years. Up to now, only red and blue laser diodes were commercially available, while green lasers (*1) were obtained by frequency conversion of infrared lasers. Gallium nitride (GaN) semiconductors, commercially available for blue LEDs, are also expected to be the key material for light-emitting devices in the green region. However, the material has been plagued with a phenomenon where the luminance efficiency shows a rapid decline with increasing wavelength.

At Sumitomo Electric, they have overcome this problem by developing a GaN crystal which inhibits the efficiency drop, resulting in room temperature pulse operation of a laser diode emitting in the pure-green region at 531nm. It is the first green laser diode in the world. Continue reading Sumitomo Electric Industries, Ltd. has successfully developed the world’s first green laser diode lasing at 531 nm

Some businesses had an unusual decline in revenue on the Fourth of July in Morro Bay, which held a laser light show in lieu of the traditional fireworks which are usually a big crowd drawer.

With the same cost of $25,000 the 30-minute Tidelands Park laser show was tagged to be an environmentally friendly alternative to fireworks show.

Hofbrau Restaurant, Great American Fish Co. and Giovanni’s Fish Market said they had near-record figures Friday and Sunday, but saw decreases in average business ranging from fifteen to twenty-five percent on Saturday compared to last year, owners said.

Owners of all three establishments said that they would be concerned if a laser show is planned again for ext year. They would definitely be sending complaints to the city representatives.

Although Mayor Janice Peters did not receive any complaints Monday afternoon after the festivities, some residents told her that they cannot see the show from their homes.

She favored the laser show as it is an environment friendly alternative which is better for Morro bay and its key species.  Morro Bay being home to a heron rookery, peregrine falcon nests and snowy plover will be best served by  having laser shows instead.

Comments received by the Morro Bay Chamber of Commerce will be reviewed and be used whether or not to have another laser show next year, CEO Peter Candela said.

“What we try to do is listen and maybe change things so we have more of a balance of what people want”, he said.  “There are a lot of different directions we could go, but it’s certainly going to be evolving”.
