| Summary: | 博士 === 國立中央大學 === 光電(科學)研究所 === 85 === In this paper, we have studied the effect of the pumping beam focus positionon the output of an end-pumping diode laser pumped solid-state laser by calculating the changes
in the overlap of the intensity distribution functionof the pump and the oscillatig beams. It is shown that the output power isstrongly pump position dependent. And, the optimized pumping position is a function of the pump beam and oscillation mode spot sizes. Our experiment results agress well with our theoretical predictions. We also propose a new type of Q-switch laser design, which is a multi-layeroptical film of electro-optical Q-switch. The major advantages of this Q-switch laser design are ultra-low operation voltage and very compact in dimension forsemiconductor laser end-pumped solid-state laser. The multi-layer optical filmeven can attached to one end of the active medium to act simultaneously as onereflector of the optical resonator. Can design an alignment free of Q-switch lase
