A High Power CH3OH Laser System Using Stark Stabilized CO2 Pump Lasers

A dual channel, 119μm wavelength laser system has been constructed for the ATF experiment at Oak Ridge. The pump lasers utilize external Stark cells for locking the CO2 laser to the absorption frequency of the CH3OH lasers. Stark plates have also been attached to the dielectric waveguide resonators of the FIR lasers to affect precise tuning of the 119 μm lasers.
