We study the Renormalisation Group flow of critical bosonic background fields in the framework of the Renormalisation Group approach to string theory. In this approach Quantum Field Theory beta-functions are the extra inputs in solving the string theory sigma-model equations. We study a Yang-Mills theory where the coupling constant diverges in the infrared limit. Also, we consired a type of theories where the beta-function has a pole in the infrared limit and it changes sign through the pole (as in N=1 super-Yang-Mills theory).
