Lasers that emit ultrashort pulses of light are used for numerous applications, but the quality of the results is limited by distortions caused by lenses and other optical components that are part of the experimental instrumentation. Researchers have developed a system that tells researchers what types of aberrations are present, which allows them to create the desired pulse at the focus that's free of distortions.
