| Citation | Distinguished for his research on ultra-short pulse laser science and technology. Sibbett, in his work on streak cameras, first demonstrated the technique of sub-picosecond chronoscopy. By synchronous repitition the streak cameras function as oscilloscopes. This was followed by his pioneering work on coupled cavity or additive pulse modelocking and, more recently, his discovery of the technique of self-modelocking. First observed in nonlinear effects in titanium-doped sapphire, this technique haas proved generally applicable and enabled the commercialisation of sub-picosecond pulses of wide tuning range. His research can be said to have led the field in this area. Finally, he has exploited the advantages of diode-pumped solid-state lasers in the field of nonlinear optics for frequency conversion by demonstration of the world's first all-solid-state optical parametric oscillator. These contribution are adding significantly to the power of laser techniques in physical investigation. |
