# Observation and Control of Laser-Enabled Auger Decay

## TL;DR

This paper reports the first experimental observation of single photon laser enabled Auger decay (spLEAD) in neon, demonstrating control over electron emission and highlighting its potential for probing electron correlation and ultrafast dynamics.

## Contribution

It provides the first experimental evidence of spLEAD and shows how phase-controlled bichromatic laser pulses can manipulate electron emission patterns.

## Key findings

- Successful detection of spLEAD in neon
- Coherent control of electron angular distribution
- Potential for probing electron correlation in complex systems

## Abstract

Single photon laser enabled Auger decay (spLEAD) has been redicted theoretically [Phys. Rev. Lett. 111, 083004 (2013)] and here we report its first experimental observation in neon. Using coherent, bichromatic free-electron laser pulses, we have detected the process and coherently controlled the angular distribution of the emitted electrons by varying the phase difference between the two laser fields. Since spLEAD is highly sensitive to electron correlation, this is a promising method for probing both correlation and ultrafast hole migration in more complex systems.
