Figure 6

(a) Dependence of the photon conversion efficiency of SPOPO on pump intensities, for both type-I and type-0 QPM designs. To show the plots clearly, different pump intensity scales were utilized for distinct pump durations. The paler part in the solid curve correspond the cases when pulse distortion exists. (b) The calculated maximum conversion efficiency versus various pump durations without compromising on the quality of mid-IR output.
