Abstract

A Stark-tuned laser operating on the 119 micron line of CH3OH has delivered reasonably high power (several tens of milliwatts at 30 Watts of pump power) while simultaneously exhibiting a doublet splitting of about 10 MHz, which is an order of magnitude larger than the modulation frequencies currently being used in plasma interferometers. Because the resonator design has allowed the attainment of both high power and high doublet splitting, this type of laser would be usable in the type of multi-channel interferometers currently employed on the large-scale plasma devices being used in magnetic fusion research.
