The concept that a laser can be made to produce short pulses by mutually phase-locking its cavity modes of different frequencies is familiar but an alternative approach is to use nonlinear frequency conversion to create synchronous outputs at different wavelengths whose combined bandwidth can support pulses much shorter than those available from a single laser. The challenge involved is to find a method of phase-locking different sources but, given the recent developments in the carrier-phase control of individual laser oscillators, there is now a timely opportunity to extend these techniques to manipulate fields at very different wavelengths and use them as building blocks to synthesise single or even sub-cycle pulses.Recent work involving coherent pulse synthesis has been restricted to mixing similar wavelengths from 2 Ti:sapphire lasers. In our proposal we aim to advance the state-of-the-art by demonstrating coherent synthesis between fs pulses from an OPO and its pump laser separated by hundreds of nm. Our approach will produce bursts of single-cycle pulses with repetition rates of tens of THz and broad-band measurements will unamgiguosly indicate that rcoherent pulse synthesis has been achieved.
