Optical detection of magnetic resonance [PDF]
Magnetic Resonance, 2020 Abstract. The combination of magnetic resonance with laser spectroscopy provides some interesting options for increasing the sensitivity and information content of magnetic resonance. This review covers the basic physics behind the relevant processes, such as angular momentum conservation during absorption and emission.

Accelerating Airy Beams Along Tunable Propagation Trajectories
IEEE Photonics Journal, 2017 We present a simple and highly efficient approach to directly generate tunable Airy beams, which can propagate along arbitrary monotonic curves. Such beams are generated by modulating a Gaussian beam imposed by tunable phase-only patterns.
