Position

Director and Professor, Electrical and Computer Engineering, at Cornell University, USA.

Thèmes de recherche

Pollock runs an experimental research program in laser development and application. Activity includes the generation of ultrashort optical pulses using advanced modelocking techniques, the development of new solid state lasers (such as Cr-ZnSe), semiconductor- diode pumping of solid state lasers, and interaction of ultrashort pulses with fiber optic devices.
Recent new work involves evanescent-coupled fiber optic devices, and the fabrication of thin-film waveguide lasers.

Research accomplishments include the discovery and development of the NaCl color center laser, which is the most powerful, stable color center laser yet discovered, and development of a tunable infrared femtosecond laser.
