| Abstract | ||
| In this work, one effect of the optical pumping power on the characteristics of a solid-state Nd:YAG laser was studied. The main parameter considered is the change in focal length of lens induced in the Nd:YAG crystal due to temperature-dependent variation in both refractive index and optical elasticity coefficient. The pumping-induced change in focal length of such lens is an important parameter in laser design as it determines how long the optical resonator may keep its stability during operation. It also assigns the main features to be considered in order to obtain the optimum characteristics of the produced laser beam. This investigation does not consider all aspects may affect laser operation but it represents a forward step to understand the intracavity limitations of solid-state, specially Nd:YAG, laser. | ||
