As sediment [quartz] is transported by wind, water, or ice, it is exposed to sunlight (“bleached”) and zeroed of any previous luminescence signal. Once this sediment is deposited and subsequently buried, it is removed from light and is exposed to low levels of natural radiation from the surrounding . Bianca . Cilento. What is a laser?. A laser is a device that emits light through the process of stimulated emission.
