Bringing complex field physics to the tabletop: A photonic stage for non-Abelian gauge fields
For most theories in physics, the order of operations has little impact on the result. When setting a dial to a certain ...
This low average signal problem was avoided in the initial demonstration of spectroscopic SRS with higher pulse energy (∼280 nJ) and 1 s dwell time. Recently, spectroscopic SRS at more modest energy ...
