Paper Abstract

Spectral broadening and the generation of new frequencies were initially observed in pulsed laser systems in the mid-1960s as an inherent feature of the uncontrollable nonlinear process such as self-focussing and self-phase modulation occurring primarily in the gain media and were looked upon as deleterious rather than a resource. With the advent of mode locked lasers to generate picosecond pulses new effects were observed. Developed by the Alfano group in bulk media external to the laser in the 1970s the supercontinuum or “white light” source has now evolved into a commercially successful and highly compact source that can readily extend over more than three octaves with spectral power densities exceeding 100mW/nm. In this presentation I will describe this remarkable evolution.
