Source: Nature Understanding Temporal Walk-off in Nonlinear Frequency Conversion Understanding Temporal Walk-off in Nonlinear Frequency Conversion What is Temporal Walk-off? Temporal walk-off occurs in nonlinear frequency conversion processes with ultrashort pulses when pulses of different frequencies have different group velocities, causing them to lose temporal overlap after propagating a certain distance. This phenomenon can limit […]
