Abstract

Highly stable room-temperature, mid-IR, GaSb-based laser diodes have been characterized at various temperatures and driver currents. Up to 54 mW of output power was demonstrated in a 3150- to 3180-nm-wavelength range with <20-nm FWHM spectral width.

Highlights

  • Ablation is used to generate the extreme pressures required to compress a fusion capsule to ignition conditions

  • Mid-IR laser diodes are required for cryogenic D2 target layering for Inertial Confinement Fusion (ICF)

  • Room-temperature mid-IR, GaSb-based laser diodes have been characterized at various temperatures and driver currents

Mid-IR laser diodes are required for cryogenic D2 target layering for Inertial Confinement Fusion (ICF). Room-temperature mid-IR, GaSb-based laser diodes have been characterized at various temperatures and driver currents. Up to 54 mW of output power was demonstrated in a 3150- to 3180-nm wavelength range with
