A stable mid-IR, GaSb-based diode laser source for the cryogenic target layering at the Omega Laser Facility.

A stable 3-microm-wavelength, GaSb-based diode operated at room temperature has been investigated as a potential laser source for cryogenic target layering at the Omega Laser Facility for inertial confinement fusion (ICF) experiments. More than 50 mW of output power has been achieved at 14 degrees C with high spectral and output-power stability.
