“…2. However, the resonant cladding structure also experiences a heat load and insures SM properties of the DMF rod fiber for large heat loads [10]. The core overlap as a function of heat load for the DMF85 rod fiber is compared to a 19cell core PCF, whose cross section is equal to the DMF rod fiber without the resonator inclusions in Fig.…”

“…Figure 6 shows the calculated TMI threshold as a function of thermal load using Eq. (10). The solid and dashed curves are calculated for R N = −120 dBc/Hz and R N = −100 dBc/Hz, and represent a TMI threshold interval depending on RIN.…”

Abstract:We present a semi-analytic numerical model to estimate the transverse modal instability (TMI) threshold for photonic crystal rod amplifiers. The model includes thermally induced waveguide perturbations in the fiber cross section modeled with finite element simulations, and the relative intensity noise (RIN) of the seed laser, which seeds mode coupling between the fundamental and higher order mode. The TMI threshold is predicted to ~370 W -440 W depending on RIN for the distributed modal filtering rod fiber.

“…In order to assess the effects of quantum defect heat generation on the SM regime of ROD fibers (in general), different design approaches have been compared through simulations [38,42]. The DMF rod fiber is compared to a standard PCF with a 19 cell core, and a Step-Index-Fiber (SIF) with equal core area and aircladding as the DMF fiber.…”

Abstract:In recent years, ultrafast laser systems using large-mode-area fiber amplifiers delivering several hundreds of watts of average power has attracted significant academic and industrial interest. These amplifiers can generate hundreds of kilowatts to megawatts of peak power using direct amplification and multi-gigawatts of peak power using pulse stretching techniques. These amplifiers are enabled by advancements in Photonic Crystal Fiber (PCF) design and manufacturing technology. In this paper, we will give a short overview of state-of-the-art PCF amplifiers and describe the performance in ultrafast ps laser systems.
