What is the point of ultrafast laser spectroscopy?

[chill_factor]

Ultrafast laser spectroscopy, as I know, is used for the determination of femtosecond events in condensed phases.

My question is, what applications do these discoveries have, or are they just for "research"?

It is used to determine the reaction mechanism. You probably already know this but, research leads to cool stuff!
