Ultrafast solutions for advanced materials science

Enabling next generation materials characterization through ultrafast laser based IR spectroscopy and high harmonic generation

Materials scientists are on a quest for tools and techniques that allow them to better characterize and develop novel materials.  Ultrafast laser based IR spectroscopy and high harmonic techniques are opening promising new avenues of inquiry for researchers in the field with the potential to revolutionize how we understand materials.

IR Spectroscopy

Infrared Spectroscopy is a foundational family of techniques used by researchers in multiple disciplines to characterize materials.  Researchers who want to analyze the dynamics of materials over short periods of time (e.g., picoseconds) and/or at high resolutions (e.g., sub-10 micron) have been limited in their ability to apply these techniques because of the lack of required high quality IR sources. In this wavelength range, there is a group of mature technologies available.  However each of the traditional light sources has a major shortcoming: Thermal emitters have low brilliance due to their incoherent nature, Quantum Cascade Lasers (QCLs) are not tunable in wavelength, and systems consisting of a Ti:sapphire laser pumping an optical parametric amplifier (OPA) with difference frequency generation (DFG) stage are cumbersome and expensive, requiring substantial laser expertise to configure and maintain.

The KMLabs Y-Fi OPA has been designed to meet researchers’ needs for a robust, tunable, compact ultrafast laser to enable advanced IR spectroscopy techniques including multi-dimensional spectroscopy (e.g., 2D IR, transient absorption, time-resolved IR spectroscopy) and tip-enhanced IR spectroscopy (e.g., near-field nanoscopy, AFM-IR, nano-FTIR).

  • Wavelength Tunability – The Y-Fi OPA provides wavelength tunability from the short-wave infrared through the long-wave infrared enabling research across several major areas
  • Signal to Noise Ratio – The Y-Fi’s class leading pulse energy, duration, and repetition rate equate to superior average power and background noise suppression
  • Robust Design – Single-box laser system that has unprecedented stability and ease of use in a laptop sized footprint

High Harmonic Techniques

Many customers are building laboratory instruments to investigate material science that has traditionally only been accessible at synchrotrons and free electron laser (FEL) facilities. Access to these facilities is challenging. XUUS is dramatically superior to the homebuilt instruments, both in terms of performance and reliability, and enables access to techniques using the extreme ultraviolet (EUV) region of the spectrum, including photoemission electron microscopy (PEEM), time-resolved ARPES, Nano ARPES, magnetics, multi-modality imaging, coherent diffractive imaging, ptychography, spin dynamics, phase transitions, charge transport, electronic and elastic properties of materials and nanostructured media, and metrology in nanostructures.
