CW ATTO Laser Introduced

20 July, 2011 Santa Clara, CA

Spectralus is pleased to introduce a new CW (continuous-wave) ATTO laser version to complement the existing pulsed versions (targeted at projection applications). This new CW-operation laser is optimized for applications that need a stable, low-noise beam, such as for biomedical and analytical instrumentation, industrial alignment, process control and aerospace/defense. Initially the CW version is available with a nominal output power of 40 mW, and is very well-suited for bioinstrument usage including cell counting/sorting, scanners, microarray readers and microscopy. As for the other versions of the ATTO laser, the power conversion efficiency is excellent. Coupling that with the highly compact affordable ATTO package makes this laser very well suited as the illumination source for portable instruments and Point-of-Care usage. In addition this laser has low intensity noise (typ 0.5% rms) and an excellent beam quality, as required for demanding instrumentation applications. More information on this new CW version is available on this web-site, or contact Spectralus directly for more detailed information.

Spectralus Corporation announced today that the U.S. Patent and Trademark Office (USPTO) has issued Notices of Allowance for three U.S. patent applications to proceed to grant. These new patents, co-authored by Stepan Essaian and Andrei Shchegrov, cover efficient microchip laser technology based on Spectralus proprietary PPMgOLN nonlinear crystals.

The first patent, entitled Compact solid-state laser with nonlinear frequency conversion using periodically poled materials, is for a solid-state microchip laser architecture based on Spectralus proprietary PPMgOLN material (protected by US patent 7,413,635). This IP is critical for the entire portfolio of Spectralus green lasers, including the newly released Atto green laser.

The second patent, entitled Solid-state laser arrays using nonlinear frequency conversion using periodically poled materials, is for a solid-state microchip laser array architecture, also enabled by Spectralus periodically poled nonlinear crystals. This patent describes laser technology suitable for scaling Spectralus microchip lasers to high power levels.

The third patent, entitled Compact, efficient, and robust ultraviolet solid-state laser sources based on nonlinear frequency conversion using periodically poled materials, describes extending Spectralus efficient laser technology to shorter wavelengths.

Spectralus CEO and President Stepan Essaian commented: This is an exciting milestone for our company. When we wrote these patent applications, we only had a proof of concept for our efficient PPMgOLN microchip laser technology. Since then, we developed industry leading products or advanced prototypes based on these inventions. With the emerging huge pico-projector market and increasing global interest in green laser technology, this IP helps to solidify Spectralus leading position in this market and significantly raises our company value for its partners.
