ABSTRACT:

In this paper the contributions on the coupling efficiency from the various portions of intersecting circular pump cavity were investigated and the approaches to increase the coupling efficiency were given in this section. Theoretical calculations of the efficiencies of pump cavities are agreeable  with experimental results.

KEY WORDS:  pump cavity, coupling efficiency, intersecting circular cavity.
