Laser Scientists Create Portable Sensor For Nitrous Oxide, Methane

Rice University scientists have created a highly sensitive portable sensor to test the air for the most damaging greenhouse gases. The device, created by Rice engineer and laser pioneer Frank Tittel and his group, uses a thumbnail- sized quantum cascade laser (QCL) as well as tuning forks that cost no more than a dime to detect very small amounts of nitrous oxide and methane.
