Reliability analysis of Nd：YAG side-pumped laser based on GO method

摘要:

本文报道了基于GO（Goad Oriented）法的Nd∶YAG侧面泵浦激光器可靠性分析，建立了Nd∶YAG侧面泵浦激光器的GO图模型，定性分析了Nd∶YAG侧面泵浦激光器的薄弱环节，定量计算了激光头中各薄弱环节的可靠性结果，包括等效故障率λ_R、等效维修率μ_R、平均无故障工作时间（MTBF）等；并定量计算了KTP晶体故障率的改善对Nd∶YAG侧面泵浦激光器可靠性提高的影响。本文中建立的GO图模型可为Nd∶YAG侧面泵浦激光的优化及可靠性评价提供理论依据。

Abstract:

The reliability analysis of Nd:YAG side-pumped laser based on GO (Goal Oriented) method is studied. The GO diagram model of the Nd:YAG side-pumped laser is established. The weak links of the Nd:YAG side-pumped laser are analyzed qualitatively, and the reliability results of each weak link in the laser head are calculated quantitatively, including the equivalent failure rate λ_R, equivalent maintenance rate μ_R, average fault-free operating time MTBF, etc. The effect of improving the failure rate of KTP crystal on the reliability of Nd:YAG side-pumped laser is quantitatively calculated. The GO diagram model established in this paper can provide a theoretical basis for the optimization and reliability evaluation of Nd:YAG side-pumped laser.
