Mid-Infrared Quantum Cascade Lasers and Laser Spectroscopy
Dr. Gmachl’s lab at Princeton researches quantum cascade laser technology as part of the Mid-Infrared Technologies for Health and the Environment (MIRTHE) organization. Quantum cascade lasers are an excellent source of coherent laser light in the mid-infrared, but there are no powerful sources of low-coherence light, such as light emitting diodes, in that part of the spectrum. My project was to create a more energy-efficient mid-infrared LED from conventional quantum cascade lasers. This technology may have applications in medical imaging and illumination. With my partner Tiffany Ko, I designed and tested a diffuser plate made from potassium bromide that scatters laser light and scrambles the beam. My research is still in the early stages of development, but my results so far showed promise, and I plan to continue the project during the year.
