Wavelength-Tunable, Sub-Picosecond Pulsed Laser Diagnostic Tool for III-Nitride Semiconductors

Abstract

The requested equipment would fill a tremendous void in Duke's capabilities, namely the ability to generate wavelength tunable sub-picosecond pulses in the UV-visible-IR spectral region. The required tools include a regenerative amplifier (RA) and pump laser, a frequency doubled and quadrupled optical parametric amplifier (OPA), and a difference frequency mixer to allow us to cover the entire spectral region from 200 nm to 15 microns. The pre-existing mode-locked Ti: S laser is used to pump the RA which in turn drives the OPA. The proposal was to develop this capability for wavelength tunable, sub-picosecond optical characterization of the important optoelectronic wide bandgap 111-N materials and heterostructures.
