 note = {We demonstrate the broadband operation of a synchronously
pumped optical parametric oscillator (SPOPO)
with a spatially dispersed beam and a fan-out type MgOdoped
periodically poled LiTaO3 (MgO:PPLT). Spatial
dispersion was generated using a glass prism placed in the
SPOPO cavity. The poling period was designed to match
the spatial dispersion and phase matching in MgO:PPLT,
and the spectral dispersion in the cavity was compensated
for using a fused silica plate, which had a negative dispersion
at a signal wavelength of 1500–1600 nm. We succeeded in
generating signal pulses with a pulse length of 81 fs, which
was approximately 1/5 of the pump pulse length.},
