Abstract
This study reports the spectral stability of a synchronously pumped optical parametric oscillator with a spatially dispersed beam. Using this method, broadband phase matching can be realized at any wavelength. However, large spectral fluctuations were observed in the signal pulses. Here, we demonstrate a stable condition under which the signal pulses have no spectral instabilities or pulse-to-pulse fluctuations. This stable condition was found through numerical simulations and confirmed experimentally.
