Laser induced breakdown spectroscopy (LIBS, or LIPS: Laser induced plasma spectroscopy) is one of promising sensor technologies with a variety of potentialities, such as online, on-site, rapid, in-situ, remote and direct analyses. The demand for these advanced analytical methods has been exponentially heightened by growing interest in environmental protection and quality control in industrial fields, and it is motivating further improvements of LIBS. The rapid progress of optical equipments for example, laser, spectrograph and photo-detector, and their price-reduction help research and development on LIBS, too. In this report, recent works on LIBS and its related technologies are reviewed. They include some innovations in optical setup for LIBS and novel approaches to various scientific and industrial applications.
