Summary on Grant Application Form |

It is the aim of this project to demonstrate a number of ways in which grating-engineered quasi-phasematched nonlinear crystals could have an important practical impact on infrared generation using femtosecond optical parametric oscillators (OPOs). The development is proposed of a variety of systems operating in the near- and mid-infrared which will exploit novel crystal configurations such as chirped-period and cascaded gratings to achieve broad output bandwidths, low pump thresholds, high efficiency and wide tunability. The majority of these sytems will be based on directly-diode-pumped femtosecond lasers, operating either at 850 nm (Cr:LiSAF) or at 1550 nm (Er-doped fibre laser). The principal intention of the work proposed here is to demonstrate that engineered nonlinear crystals can be used to produce practical near- and mid-infrared diode-based femtosecond sources. A further aim is to investigate how engineered gratings can be used in a short-pulse femtosecond OPO to produce extremely broadband idler radiation. A final goal of the project is to determine the performance of aperiodically-poled crystals in allowing efficient frequency doubling of broadband infrared femtosecond pulses for pulse measurement applications.
