| 摘 要： | 目的:探讨Visx20/20B准分子激光治疗系统激光腔压力与发射激光强度的关系,提出保证激光强度的最佳激光腔压力。方法:保证其它条件不变,改变激光腔压力,观察激光强度随压力的变化情况。结果:激光强度随激光腔压力增大而增加,但其激光强度增加幅度随压力的增加而逐渐减小。结论:最佳激光腔压力应在0.26MPa-0.27MPa之间,这样既节约成本,又保证足够的激光强度。

| Abstract: | Objective:Discuss the relation between the laser cavity's pressure of the Visx20/20B Excimer laser system and the laser intensity. Bring forward the best laser cavity's pressure of ensuring the laser intensity. Methods:Ensure other factors are changeless,then change the pressure of laser cavity, Observe the variational rule of the laser intensity. Results:The laser intensity increase along with the pressure increasing of the laser cavity, but the extent of the laser intensity minish gradually long with the pressure increasing of the laser cavity. Conclusion:The best laser cavity's pressure is between 0.26MPa to 0.27MPa. It not only can save cost,but also can insure the enough laser intensity. |
