Improving our understanding of chemical dynamics, biological transformations, and charge carrier mobility is essential to the understanding and advancement of science and technology in a wide range of areas. Therefore, ultrafast multi-color pump-probe techniques are definitely important tools for such type of research.

In the study “High power multi-color OPCPA source with simultaneous femtosecond deep-UV to mid-IR outputs” recently published in Optics Letters, ICFO researchers Matthias Baudisch, Benjamin Wolter, Michael Pullen, and Michaël Hemmer, led by ICREA Prof. at ICFO Jens Biegert, have described a femtosecond multi-color optical parametric chirped pulse amplifier (OPCPA) with simultaneous outputs from the deep-UV to the mid-IR with optical synchronization. The results of this study have been highlighted in the “Spotlight for Optics” review section of the OSA journals.

As mentioned in the review, the researchers used optical synchronization of a mid-IR optical parametric chirped pulse amplification system and were able to demonstrate MW femtosecond (fs) laser pulses generated with high stability at various wavelengths: 3100, 1620, 810, 405, and 270 nm. With their technique, they were able to prove that it is possible to reveal ultrafast dynamics of materials at unexplored wavelengths, since the wavelength range of high peak fs pulse outputs range from the deep UV to the mid-IR.
