摘要:

通过一维声光调Q开关晶体内的声压分布,得到一维声光Q开关晶体内部衍射效率的空间分布。再通过计算一维Q开关衍射效率的空间分布,得到二维声光调Q开关晶体中超声场的空间分布,进而得到晶体中衍射效率的空间分布。研究发现在相同驱动功率下,二维声光调Q相比一维声光调Q,在关断损耗上有较大提高,二维声光调Q衍射效率极大位置在z=2 mm平面处。

关键词: 二维声光Q开关, 衍射效率, 激光器

Abstract:

This paper discusses the sound pressure distribution within the crystal of onedimensional acoustooptic Q switch,and obtains the diffraction efficiency distribution.The computation of the diffraction efficiency distribution of onedimensional and sound pressure distribution of twodimensional gives the diffraction efficiency distribution within the crystal.It is found that under the same driving power,the loss of twodimensional is larger than that of onedimensional with the highest efficiency at z=2 mm.

Key words: twodimensional acoustooptic Q switch;diffraction efficiency;laser
