A novel solid-state laser technology for wavelengths near 220 nm overcomes limitations of current-generation UV lasers and gas discharge lamps.TIM SMEETON, KARL WELNA, EDWARD BOARDMAN, RISHANE PEREIRA, VALERIE BERRYMAN-BOUSQUET, SHARP LABORATORIES OF EUROPE LTD.Advances in sensor technologies and the more widespread deployment of sensors are continually improving safety, quality of life and industrial productivity. Many of the most reliable chemical, biological and gas sensors are in some way based on light, with current technology exploiting wavelengths from deep ultraviolet to far infrared. Within this field, ultraviolet light with wavelengths between 210 and 230 nm in the ultraviolet C (UVC) spectral range has a vital role because of the strong and specific interaction between these wavelengths and many analytes, especially those measured during...Read full articleRelated content from Photonics MediaARTICLESVIGO Photonics’ IR Sensors Board NASA’s Orion: Week in Brief: 06/16/22III-V Epi, a provider of compound semiconductor wafer foundry services, completed the Innovate UK-funded, SHARK-VECSELs project with the University of Strathclyde.
