The rover Curiosity has zapped a fist-sized Martian rock with its laser, producing a cloud of ionized plasma that will be analyzed by Curiosity’s spectrometers. The rock – christened “Coronation” by NASA scientists – was subjected to 30 laser pulses over 10-second period. Each laser pulse delivers more than a million watts of power for […]
Researchers at the University of California, Berkeley (UC), have reached a new milestone in laser physics with the creation of the world’s smallest semiconductor laser, capable of generating visible light in a space smaller than a single protein molecule. Described in the journal Nature, the research breaks new ground as the scientists not only successfully […]
