Abstract : The electro-optic sampling system developed under AFOSR contract no. F49620-85-0016 has been the workhorse for high speed measurements made in this lab. This report documents the continuing effort to improve this tool and highlights its most recent uses. In addition, we report the development of a time-lens, a new tool that gives us electronic control of the shape of optical pulses. The development of a time-lens has opened tip a new field of research. It is a tool to electronically control the temporal characteristics of optical pulses just like glass lenses control the spatial characteristics. Our results to date include the creation of 7 ps pulses from a CW laser, active focusing (compression) of 55 ps pulses down to 2 ps, and demonstration of the time- reversal properties of time-lenses. A Ph.D. thesis detailing the Stanford time- lens and pulse compression experiments is included as an appendix. Electro-optic sampling, Time-lens, Erbium doped fiber amplifiers
