The femtosecond laser research lab has recently acquired a new laser system. This system incorporates both an amplified cavity and an optical parametric amplifier (OPA), expanding the lab’s capabilities in several ways.
The amplified cavity increases the energy of the laser pulses to 5 millijoules (mJ) at a central wavelength of 800 nanometers (nm) with a pulse duration of 35 fs. This allows researchers to investigate light-matter interactions at higher intensities, providing access to previously unexplored material responses in the femtosecond regime.
The integrated OPA offers tunable laser output, ranging from 480 nm in the visible region to 2 micrometers (µm) in the mid-infrared. This tunability enables researchers to target specific material properties with greater precision.
The addition of this new laser system enhances the lab’s capacity for research in various areas, including:
- Deeper Probing: With amplified pulses, we can delve deeper into material responses, investigating previously inaccessible phenomena.
- Tunable Precision: The OPA allows us to tailor the laser wavelength to specific material properties, enabling highly targeted and precise manipulation.
- Broadened Research Horizons: This powerful duo opens doors to new research avenues in various fields, including nonlinear optics and ultrafast spectroscopy.
The addition of this laser system positions our lab at the forefront of ultrafast laser research.
