This paper presents effects of tilt and decenter caused by vibration on spot size and shape. The ideal spot shape for a laser source can be modeled as a Gaussian curve. In high-power laser systems, focusing the laser beam on a target is very crucial to increase the power density. The laser spot size should be small to focus the energy on a small area on the target adequately. Thus, it is necessary that the optomechanical system mustn’t be affected by environmental factors such as temperature, humidity, vibration, etc. In this study, the effect of vibration on optomechanical design is examined. Results of optomechanical design analysis performed by using the finite element method are take into account to get tilt and decenter values as an input. The analysis is based on the MIL-STD-810G standard. As a result of the analysis, tilt and decenter values exposed to optomechanical design are determined and these values were provided as the input to the optical design.
