  100-200 MeV range ERL-FELs gen­er­at­ing few cycle short, high in­ten­sity mid-IR pulses with tens of MHz rep­e­ti­tion rates might be­come at­trac­tive tools in var­i­ous strong field ap­pli­ca­tions. In a re­cent study [1] a mode locked cou­pled FEL os­cil­la­tor scheme has been pre­sented to pro­duce multi-mJ level, ul­tra-short (<10 cy­cles) pulses tun­able within the en­tire IR re­gion. In this work an im­proved cou­pled FEL os­cil­la­tor scheme is de­scribed. The cou­pled sys­tem op­er­ates uni­di­rec­tion­ally (feed­back in the re­verse di­rec­tion less than 10-8 level). The var­i­ous op­er­a­tional regimes of the sys­tem are dis­cussed. Some of the con­clu­sions stated in [1] have been re­vised.
