TL;DR: This work shows how magneto-optical spin detection can be used to determine the location of a spin associated with a single nitrogen-vacancy centre in diamond with nanometre resolution under ambient conditions, and demonstrates the use of a single diamond spin as a scanning probe magnetometer to map nanoscale magnetic field variations.

TL;DR: In this paper, a femtosecond erbium-doped fiber-optic laser was used to produce single-cycle light pulses with a pulse duration of 4.3

TL;DR: Individual nanometer-sized plasmonic antennas are excited resonantly with few-cycle laser pulses in the near infrared, and the strong third-order signal allows direct measurement of a subcycle plAsmon dephasing time of 2 fs, highlighting the efficient radiation coupling and broadband response of the devices.

TL;DR: In this article, the authors exploit frequency-resolved optical gating to directly investigate plasmon response times of different antenna geometries resonant in the near-infrared.

TL;DR: A compact coherent anti-Stokes Raman scattering microscope based on a widely tunable picosecond Er:fiber laser is presented and a first imaging application in the spectral region of CH stretch vibrations is demonstrated.
