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
