LIBS (Laser-induced breakdown spectroscopy) is a technique which can identify the composition of a**substance by ablating a minute quantity, using a short pulsed laser and recording the emission spectrum**produced as ions in the plasma recombine. Sciencetech has a long background in manufacturing precision**spectroscopic equipment and through this engage grant will partner with Dr Sanderson to develop and test a**compact LIBS instrument capable of rapid setup utilizing high repetition rate, moderately powered nanosecond**laser sources available in the laboratory in Waterloo. The aim will be to prototype a design which is a relatively**economical and flexible product suited to today's market.**The new design will utilize moderate powered kHz, compact nanosecond laser in waterloo, and compare**results with a more conventional power laser system also available. To enhance the LIBS signal, plasma**characteristics will be modified using pressurized and evacuated environments. Furthermore the high**repetition rate of the laser source will be utilized by scanning the target. Parabolic light collection will be**utilized in conjunction with fibre coupled spectrometers, to maximize signal collection and minimize costs.**In addition to potential direct economic benefit to Sciencetech through sales of the newly designed LIBS**instrument, success of this project will lead to a new commercial LIBS molecular imaging instrument which is**attractive for a number of research and industrial applications. This can enhance Canadian competitiveness in**several industrial areas, health agriculture and manufacturing alone would constitute a multi-billion dollar**segment of the Canadian economy.
