Mitsubishi Electric Testing Wind LIDAR ・Water Vapor DIAL, Including Laser Amplifier with World’s Highest Output, for Early Forecasting of Torrential Rain
TOKYO, October 11, 2018 – Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it has started demonstration testing of a new system equipped with wind LIDAR (light detection and ranging) and water vapor DIAL (differential absorption LIDAR) measuring methods for the early forecasting of torrential rain.
The system incorporates a newly developed high-output-power waveguide laser amplifier that delivers what is believed to be the world’s highest output, 15.8 millijoules, using an a single-frequency pulse laser in the 1.5μm wavelength, which is not harmful to human eyes.
The tests are expected to demonstrate that the system simultaneously measures water vapor in the air and upward air currents, which cause cumulonimbus clouds, quicker, more accurately and in a wider range compared to conventional alternatives.
Going forward, Mitsubishi Electric expects to make further improvements prior to launching a commercial system for the extra-early forecasting of torrential rain.
