Description

We investigate and develop new infrared (1.5-12 μm) materials, devices, and technologies that have potential for high lasing efficiency, broad wavelength tunability, and robust operation. Research includes exploration and development of new solid-state laser media such as Cr2+ and Fe2+ doped ZnSe and rare earth doped ceramic lasers. We are interested in lasers operating in cw, Q-switched, and modelocked modes. Rapid frequency tuning, beam control via guiding structures, and beam switching are also performance issues under investigation. Infrared lasers (bulk, fiber, and semiconductor types) are being developed for use as pumps of new quasi-phasematched nonlinear media such as orientation patterned gallium arsenide. Areas of interest include spectroscopy of infrared laser materials, novel waveguide laser demonstrations, infrared beam transport in fibers and waveguides, and infrared nonmechanical beam steering. Facilities are available to perform spectroscopic measurements of absorption, excited-state absorption, fluorescence, and fluorescence lifetime. A variety of lasers are available for experimental use including Nd:YAG, Ar-ion, Ti-sapphire, Tm fiber, and Tm,Ho:YLF; semiconductor lasers operating at 0.8 μm, 1.5 μm, and 1.9 μm are also available. Lab facilities are available for measuring lasing efficiency, spectral content, power, beam quality, ultrashort pulse characterization, and thermo-optic properties of new laser materials.
