Time-resolved spectroscopy is a technique used in spectroscopy to study the dynamic processes in molecules, atoms, or materials by measuring how their optical properties change over time after they are excited by a light pulse. This technique is particularly useful for investigating fast processes such as chemical reactions, energy transfer, and molecular dynamics on timescales ranging from femtoseconds (fs) to nanoseconds (ns) or longer.

The sample is excited by a short pulse of pulse of light. This pulse temporarily excites the molecules or atoms to a higher energy level. After the excitation, the molecules or atoms return to their ground state but while that is happening various transient states can be formed. By measuring the sample’s spectrum we can create a time-resolved spectrum, similar to multiple photos taken in quick succession of the sample. At MPBC we offer various pulsed lasers with a wide range of wavelengths and output powers, perfect for time-resolved spectroscopy.
