Pulse wave analysis in normal pregnancy: a prospective longitudinal study. [PDF]

, 2009
Outside pregnancy, arterial pulse wave analysis provides valuable information in hypertension and vascular disease. Studies in pregnancy using this technique show that vascular stiffness is raised in women with established pre-eclampsia.

High average power, high energy, femto-second fiber chirped pulse amplification system [PDF]

, 2007
We have demonstrated an Yb-fiber laser system incorporating a CFBG stretcher, bandwidth optimised amplifiers and dielectric grating compressor. The system produced 135 W average power with pulse energy of 13.5 µJ.

An efficient wavelength converter exploiting a grating based saw-tooth pulse shaper [PDF]

, 2008
We experimentally demonstrate the generation of picosecond triangular optical pulses using a superstructured fiber Bragg grating and show experimentally that use of this pulse shape can provide a three-fold improvement in conversion efficiency relative ...

Pulse retiming based on XPM using parabolic pulses formed in a fiber Bragg grating [PDF]

, 2006
We experimentally demonstrate a novel all-optical all-fiberized pulse retiming scheme incorporating parabolic pulses generated in a linear fashion through pulse shaping in a superstructured fiber Bragg grating. The scheme relies on chirping the signal to
