Scientists are using this extended comb to study the fine structure of atoms and molecules with extreme ultraviolet laser light. (scientificamerican.com)
Together with Rangaswamy Srinivasan and Samuel E. Blum, for their discovery of pulsed ultraviolet laser surgery, wherein laser light cuts and etches biological tissue by photoablation with minimal collateral damage, leading to healing without significant scarring. (osa.org)
The technique, called Ultrafast photomodulation spectroscopy (UPMS), uses ultraviolet laser pulses of femtosecond duration to change the refractive index of silicon in a tiny area on the photonic chip. (sciencedaily.com)
