The author presents a thorough convergence rate analysis of Laguerre spectral approximations for analytic functions. They show that the remainder of Laguerre interpolants can be expressed as a contour integral along the parabola with which they prove that Laguerre interpolants converge at the same root-exponential rate as their projection counterparts.
