Optically Timed Submillimeter Time-of-Flight Mass Spectrometry
Analytical Chemistry, 2003 We demonstrate that using intense femtosecond laser pulses to optically time ion flight can lead to a miniature time-of-flight mass spectrometer. After laser ionization, the molecular ion is accelerated by a static electric field and detected using a second, delayed laser pulse.
