The computation of Q-switched laser pulses

  • Published:
Journal of Applied Spectroscopy Aims and scope

Abstract

Two methods for computing the single pulse of three- and four-level lasers with instantaneous Q-switching are described. The first method makes it possible to calculate the energy, power, and duration of the pulse. The second method, based on the approximation of the population inversion by means of suitable functions, yields its shape. The analytical solutions are compared with those obtained on an electronic digital computer. The optimal losses and limits of applicability of the formulas derived in the case of noninstantaneous Q-switching are determined.
