abstract = {<p style="text-align: justify;">High-order correction terms to the expression of the field of circularly polarized 
Gaussian laser are derived. Terms up to seventh order in the small dimensionless 
spatial parameter are explicitly presented. Using the test particle simulation programs, 
the CAS (Capture &amp; Acceleration Scenario) phenomenon in the circularly polarized 
field has been proved, and the difference efficiency of CAS scheme between the 
circularly polarized field and linearly polarized field has been investigated, 
further more the electron dynamics obtained by the paraxial approximation, the 
fifth-order correction, and the seventh-order correction are compared in detail. 
The numerical calculations show that the results of three corrected models coincide 
with each other very well for $kw_{0}&gt; 60$, and the difference of the three corrected 
models is very conspicuously for $kw_{0}\leq 50$. Then the ranges of the electron 
incident momentum for the CAS scheme in circularly polarized field to emerge are 
examined. This study is of significance in designing experimental setup to test 
CAS and helpful in understanding the basic physics of CAS.</p>},
