Resumo
This work presents a comparative study between
single-clad (SCF) and double-clad (DCF) fiber designs, focusing
on modal propagation and tolerance to the transverse mode
instability (TMI). Analytical solutions for LPmn modes and
numerical simulations are used to analyze the transverse intensity
distributions and the influence of structural parameters on the
TMI onset threshold in high-power fiber lasers. Results show
that DCFs exhibit greater tolerance to TMI, attributed to the
broader transverse mode distribution in lower-index regions,
which enhances optical confinement and thermal dissipation.
