Nonlinear optical processes for the mid-IR region
Abstract
The 2 - 5 micron (mid-IR) region is of interest for a number of applications. Efficient up-conversion and down-conversion techniques are being developed to obtain optical sources at mid-IR wavelengths. These techniques are reviewed and recent results using AgGaSe2 are reported. Gain in AgGaSe2 as high as 13 has been observed with a pump wavelength of 1.73 microns and a signal wavelength of 3.39 microns. Optical parametric oscillation in the 2.9 - 6.8 micron region has also been demonstrated.
