How to generate a Pulsed Laser Source by a Mach-Zehnder switch and AWG-5000 Waveform Generator

Department of Physics, Humboldt-Universitaet zu Berlin just published a nice paper about:

 

Collective excitation and decay of waveguide-coupled atoms:
from timed Dicke states to inverted ensembles

 

The collective emission of radiation by an ensemble of atoms is a central problem in quantum optics that has recently seen renewed interest in the context of optical quantum technologies. There, the super- and subradiant states that emerge when a propagating light field couples to a spatially extended ensemble of emitters can be used as a resource to implement novel protocols, e.g., in the context of quantum information, quantum communication, and frequency standards. The underlying, so called timed Dicke regime has been extensively studied, both theoretically and experimentally, e.g., with ensembles of laser-cooled atoms in the optical domain.

Pulsed laser beam and AWG-5000 Waveform Generator

The application demonstrate how to generate a pulsed laser beam starting from a continuous wave laser, using the amplitude modulation of a Mach-Zehnder optical switch, which is controlled by the the AWG-5000 Arbitrary Waveform Generator. The unique feature of AWG-5000 of 5Vpp amplitude with 110ps rise time, allows the generator to drive directly the Mach-Zehnder optical switch.
