Ultra-broadband pulse evolution in optical parametric oscillators
Optics Express, 2011 Ultrashort-pulse evolution inside a optical parametric oscillator is described by using a nonlinear-envelope-equation approach, eliminating the assumptions of fixed frequencies and a single χ((2)) process associated with conventional solutions based on the three coupled-amplitude equations.
