Description
Marcus Illguth and co-authors describe a 2025 study of a laser test for chlorine in cement paste. Finding chlorine inside drilled concrete cores matters for judging damage risk. The laser dose must stay tiny to limit fumes and spare the sample, yet tiny doses give weak signals.
Their setup fires a laser pulse at a very low energy, then boosts the glow with microwaves. The boost grew the plasma cloud by a huge factor without extra surface burn. Signal strength rose with microwave power and pulse length. A test line for chlorine shone at a clear peak, and a fit line spanned the range of interest. The lowest amount the test could find sat near a fifth of one percent by weight.
