Sub-Picosecond Laser for Investigating Oscillator-Waveguide Interactions

摘要

This project purchased a diode-pumped, mode-locked Ti:Sapphire short- pulse laser system that would produce ultrashort pulses in the 800 nm wavelength range. Acquiring the laser makes it possible to investigate the interaction between molecular or nanoparticle resonances and the propagating electromagnetic surface modes (i.e., surface waves) supported by nearby planar thin-film structures. Investigations in the linear optical regime have already demonstrated that this interaction produces surprisingly strong linear optical effects. Acquiring the requested short-pulse laser system enables the existing ARO-sponsored research program focused on linear effects to be extended to include the nonlinear regime.
