Tiivistelmä
Antenna-coupled microwave radiation is used to enhance the sensitivity of laser induced breakdown spectroscopy (LIBS). Limit of detection on low laser pulse energy is enhanced by factor of 93. Improved detection is mainly due prolonged plasma lifetime which enables use of longer signal integration times.
