BNL scientist Ralph James was recognized for exceptional technical accomplishments and leadership leading to advances in nonlinear optics and optoelectronic sensors for laser, spectroscopy and imaging. Ralph James studies how the properties of semiconductors change when exposed to intense laser pulses. His date are used to make infrared lasers work effectively for a wide variety of applications, from medical to military. The research involves the use of high-intensity laser pulses to thermally process semiconductor crystals for producing solar cells. James also developed a new class, solid-state radiation detectors that can efficiently detect both x-rays and gamma rays at room temperature. Also they identify specific isotopes responsible for the radiation. There are a variety of applications including medical imaging, nuclear nonproliferation, environmental monitoring, and nuclear and space sciences.
