High peak/average power picosecond pulsed MOPA system with tapered large mode area double-clad Yb-doped fiber [PDF]
EPJ Web of Conferences, 2022 In this paper, a high peak/average power picosecond pulsed master‑oscillator power‑amplifier (MOPA) system utilizing tapered large mode area double-clad fiber (T-DCF) is presented. In a high average power regime, we report a pulsed MOPA laser system with

Large-area single-mode photonic bandgap VCSELs [PDF]
Journal of Lightwave Technology, 2004 We demonstrate that the photonic bandgap effect can be used to control the modes of large area vertical cavity surface emitting lasers. We obtain more than 20 dB side mode suppression ratios in a 10-micron area device.

Large Mode Area Fibers for High Power Applications [PDF]
Optical Fiber Technology, 1999 We review our recent work toward designing large mode area fibers for high power applications. We show that appropriately designed doped multi-mode fibers can be used to provide robust single-mode output when used in fiber laser cavities. Single-mode (SM) fiber mode field diameters of ~35µm are demonstrated with record SM pulse energies of 0.5mJ at ...

Influence of Pedestal Fiber Splice on Tm-Doped Fiber Laser Performance
IEEE Photonics Journal, 2023 The influence of Tm-doped pedestal fiber splice on the output performance of a large-mode-area (LMA) Tm-doped fiber laser (TDFL) has been investigated. Arc-fusion induced refractive-index deformation leads to laser leakage from the core to the pedestal ...

The effect of periodicity on the defect modes of large mode area microstructured fibers
Optics Express, 2008 It is well known that periodic variations in refractive index can be used to create guidance in an optical fiber via photonic bandgap effects. It has also been shown that periodic structure in index-guiding microstructured fibers can lead to the guidance of additional leaky higher-order modes due to bandgap effects.
