Abstract

We demonstrate optical time-domain spectroscopy from femtoseconds to nanoseconds using an ultrafast dual-fiber-laser system with kilohertz continuous scanning rates. Utilizing different wavelengths for the pump and probe beams, we exploit this system’s broad range of timescales for quantitative studies of thermal transport and the detection of coherent spin and lattice excitations in epitaxial magnetic thin films. The extraordinary temporal dynamic range provides a way to connect the fast and slow timescales in the observation of dissipation and decoherence processes.

  19. The heat diffusion model (equations 2-7 from [15]) can be applied if the time constant of heat diffusion in film (?f) and interface time constant (?i) follows ?f/?i = d ?k / kf <1 (equation 10), where d is the film thickness. If ?k ~ 108 to 109 W/m2K and kf is from few tens to few hundreds W/Km then d should be < 100 nm, which verifies that d for our samples (70 nm) satisfies this criterion.
