Abstract

We adapt nonlinear stimulated Raman exact passage (NL-STIREP) technique first proposed by Dorier et
al. [Phys. Rev. Lett. 119, 243902 (2017)] to fractional population transfer in configurations and extend it
to nonlinear N-pod systems. We use NLF-STIRAP technique in a system and indicate that, NLF-STIREP
technique can guide the dynamics of the system as efficiently as a NLF-STIRAP but with considerably smaller
Rabi frequency amplitudes. We implement NLF-STIREP technique in fractional creation of ground molecular
Bose-Einstein condensates (BECs) from atomic BECs and show that, this technique is robust with respect to
changes in the time delay between the pulses and pulse intensity.
