Laser Scanning Lends Credence to Theory of Brain Circuitry
Laser Scanning Lends Credence to Theory of Brain Circuitry Nerve cells in the brain can rewire and fine-tune themselves by forming connections with neighboring cells. Researchers in Canada made the discovery using timed visual stimulation and multi-photon laser-scanning technology while examining brain development in Xenopus tadpoles.

WHITE PAPER
DILAS Diodenlaser GmbH - High-power Visible Spectrum Diode Lasers for Display and Medical Applications - Beam Sources with Tailored Beam Quality and Spectral Characteristics High-power Visible Spectrum Diode Lasers for Display and Medical Applications - Beam Sources with Tailored Beam Quality and Spectral Characteristics
DILAS Diodenlaser GmbH

Improved beam shaping concepts allow coupling of red and blue diode lasers into smaller fibers. For medical applications beam sources with narrow wavelength distribution in the blue spectral region were developed. Modules up to 100W in a 400µm NA0.22 fiber were realized. Progress in manufacturing technologies allows for coupling of more than 25W into a 200µm NA0.22 fiber in the blue wavelength range.
