  In this paper, we report on a singly resonant optical parametric oscillator
(OPO) pumped by an amplified spontaneous emission (ASE) source. The pump
focusing conditions allow non-collinear phasematching, which resulted in a 230
nm (190 cm$^{-1}$) spectral bandwidth. Calculations indicate that such
phasematching schemes may be used to further broaden OPO spectral bandwidths.
