Complete regularity of growth for some classes of entire functions of exponential type represented by Вorel integrals and power series

New tests are obtained for the regularity of growth of entire functions of exponential type that are represented as power series $F(z)=\sum_{n=0}^\infty\frac{a_n}{n!}z^n$ and Borel (Laplace) integrals $F(z)=\int_Lf(\tau)e^{z\tau}\,d\tau$.
