Researchers at the University of Illinois at Urbana-Champaign and Nuvonyx Inc. in Bridgeton, Mo., have developed a flared semiconductor laser in which the strength of the waveguide decreases as the width of the laser increases, resulting in optimal single lateral mode control over the entire length of the device. The group envisions several applications of the laser, which produces up to 650 mW of 1040-nm radiation, including use in fiber amplification pumps, free-space communications and direct diode welding. Output powers of 650 nW have been produced by a semiconductor laser that...Read full article
