Abstract:

This report summarizes research done on a far infrared integrated optics, b a step-tunable coherent far infrared source, and c a continuously tunable near infrared and far infrared source. The far infrared optics work has required developing a stable far IR optically pumped laser which is described in detail. One of the principle problems in this effort is that of the output laser mirror. The step-tunable coherent far IR source uses frequency mixing in a dielectric waveguide to achieve phase matching. The continuously tunable source is based on a nonlinear action in a material GaAs which has both a Raman and an IR active mode. A problem with this work is that of developing a laboratory CO2 pump source and the damage problem of the crystal material.
