Abstract : Significant progress has been made in the first month in setting up the equipment in preparation for producing chaotic behavior of a CO2 laser. The project goal is to synchronize and control chaos in a CO2 and other lasers, and thereby increase the power in ensembles of coupled laser sources. One method of including chaotic behavior in a CO2 laser is to modulate the beam in the cavity with a frequency between 50 and a 100 kHz. The project has designed two schemes to achieve this modulation. These are through the modulation of the high voltage by inductive coupling and the modulation of the beam by a CdTe electro-optic modulator (EOM). Modulation of the beam using modulation of the high voltage has been achieved in the laboratory this month. This was accomplished by modulating the high voltage on the laser using an inductor connected to the anode of the laser. Modulation of the laser plasma was confirmed by detecting modulation of the plasma with a light by using a photomultiplier tube. Analysis of the chaotic regime awaits arrival and check-out of the HgCdTe detector.
