摘要: Abstract In this Letter, the propagation properties of off-axis cosh Gaussian (ChG) beam combinations through a first-order optical system are demonstrated analytically and numerically. For cases coherent incoherent ChG combinations, our results illustrate that quality combination is better than one, both which presented by M 2 -factor power in bucket (PIB). The kurtoses, for cases, show profiles platykurtic except extreme reduced case, i.e., beam.
