Simplified One-Beam 2D Electronic Spectroscopy using a Millijoule Amplifier and HCF

Coherent two-dimensional spectroscopy (CMDS) represents a powerful group of spectroscopic techniques with the unique ability to reveal couplings between different states of a system, as well as their relaxation timescales. These methods range from two-dimensional infrared (2DIR) used to probe vibrational states, to 2D electronic spectroscopy (2DES) that examines electronically excited states in molecules, semiconductors and nanoparticles. The complexity in practice – optical, mechanical, electronic – of these methods has limited their use to a relatively small group of developers and users. However, the situation is rapidly changing with the advent of rugged ultrafast amplifiers, turnkey pulse shapers, and other off-the-shelf components.
