GAITHERSBURG, Md., Sept. 6, 2006 -- Gold nanoparticles are highly efficient and sensitive handles for biological molecules being manipulated and tracked by lasers, but they also can heat up fast -- by tens of degrees in just a few nanoseconds -- which could either damage the molecules or help study them, according to scientists at JILA, a joint institute of the National Institute of Standards and Technology (NIST) in Gaithersburg and the University of Colorado at Boulder.A gold nanobead, trapped with 205 mW of infrared laser light, heats up to about 75 °C or 167 °F (shown in dark red) and the temperature in the surrounding area...Read full articleRelated content from Photonics MediaARTICLESOptical Clock Uses Laser Tweezers to Manipulate AtomsJILA physicists have demonstrated a new atomic clock design that uses laser tweezers to trap, control, and isolate atoms.

Of all the solid-state laser crystals, it has stood the test of time best. Its high gain, narrow linewidth, low threshold and physical properties make it a most versatile laser material for a variety of applications.The ubiquitous Nd:YAG laser has played many roles over the years. For the military, it has provided rangefinding and target designation capabilities.
