Trace gas detection based on laser absorption spectroscopy (LAS) is a powerful technique due to its high sensitivity and selectivity, and it is widely used in many fields. Most of current works are performed using a single frequency laser targeting only one species. Study of the interaction between different components needs simultaneous measurement of multi-species, which is still a challenge.
