Femtosecond Amplifiers and Microlasers in the Deep Ultraviolet

Abstract : This program pursued new sources (and amplifiers) of coherent and incoherent radiation in the ultraviolet and visible regions of the spectrum, as well as their applications in photochemistry and medical therapeutics. Research highlights include: (1) Demonstration of lasing in the visible and near-infrared from Na and Rb, respectively, by photoassociating alkali-rare gas atomic pairs, (2) Observation of the collapse of a 3-level laser system by tuning the energy defect between the pumped and lasing states- this resolves a fundamental question in quantum electronics, and (3) Demonstrating a new micro/nano optical amplifier well-suited for routing optical power in a scattering medium such as human tissue.
