We demonstrate a picosecond singly resonant optical parametric oscillator (OPO), which is synchronously pumped by a source consisting of a gain-switched laser diode and a chain of Yb-doped fibre amplifiers. The OPO produces up to 7.3W at 1.54µm (sig

Laser-generated XUV and soft x-ray radiation sources using high-harmonic generation (HHG), typically producing 108 photons per pulse per harmonic (~5nm to ~50nm) in a coherent low-divergence beam [1], are a promising source for nanometer scale imagin

We experimentally investigate the fidelity of parametric transfer of ultrashort pulse characteristics from the near-infrared pump to mid-infrared idler in a synchronously pumped optical parametric oscillator. The sonogram technique is used to charact

Parametric transfer in a synchronously pumped optical parametric oscillator: toward coherent control
Mid-infrared (MIR) ultrashort optical pulses with electronically programmable shapes are a key experimental ingredient in using light to control the outcome of chemical reactions involving molecules whose vibrational energy levels are in the interest

Short pulse X-ray radiation at nanometer wavelength provides a nanoscale source for a wide range of applications in nanoscience and technology. We demonstrate the generation of coherent ultrafast soft X-rays by high harmonic generation in a capillary

The ability to fabricate nonlinear optical materials with periodic or aperiodic spatial modulation of the nonlinearity has provided an enormous increase in the capability and versatility of frequency-conversion devices. This talk will start with a

The synchronously pumped optical parametric oscillator (SPOPO) has undergone major developments in the past decade. Quasi-phase-matched nonlinear materials, such as periodically-poled lithium niobate (PPLN) and the availability of higher pump power h

Synchronously pumped optical parametric oscillators (SPOPOs) are efficient sources of tunable ultrashort pulses, with low threshold average power requirements, since gain is defined by peak power. An attractive material for such devices is cadmium se
