We simulate the transient behaviour of a self-starting holographic las
er oscillator using a numerical model which can account, to arbitrary
strength, for one, two and four gain gratings within the saturable amp
lifying medium. The dependence of output energy on parameters such as
intracavity gain and output coupler reflectivity is investigated, ther
eby enabling the optimisation of extraction efficiency and the underst
anding of oscillation and grating dynamics. (C) 1998 EIsevier Science
