Abstract
Nonlinear spectral modulation and broadening have been observed in qua si-phase-matched KTP waveguides near 850 nm, indicative of self-phase modulation that is due to cascaded second-order processes. Numerical b eam-propagation simulations indicate nonlinear peak phase shifts large r than pi for 600 W of peak power in a 2.8-mm-long guide.
