Theoretical analysis of optical fiber laser amplifiers and oscillators

Applied Optics, 1985
Using the formalism of mode overlap, a theoretical analysis of optically pumped fiber laser amplifiers and oscillators is developed. The concept of normalized overlap coefficients is introduced to account for the effects of the transverse structure of the interacting signal and pump modes on the device characteristics.

Efficient Femtosecond Mid-IR Optical Parametric Generation at 10 MHz Pumped by a Mamyshev Fiber Oscillator and Amplifier

Laser Congress 2023 (ASSL, LAC), 2023
We report highly efficient (~60%) femtosecond mid-IR optical parametric generation at 10-MHz repetition rate exploiting zero-group-velocity-mismatch condition in 19-mm-long PPLN and 42-mm-long MgO:PPLN crystals. We obtain 300-fs signal pulses with 3.4-4.1 μm idlertuning.

Fiber-optic parametric amplifier and oscillator based on intracavity parametric pump technique

Optics Letters, 2009
A cost-effective fiber optical parametric amplifier (FOPA) based on the laser intracavity pump technique has been proposed and demonstrated experimentally. The parametric process is realized by inserting a 1 km highly nonlinear dispersion-shifted fiber (HNL-DSF) into a fiber ring-laser cavity that consists of a high-power erbium-doped fiber (EDF ...

Optical properties of high power S-band fiber oscillators and amplifiers

SPIE Proceedings, 2014
S-band fiber lasers, one type of ytterbium doped fiber lasers(YDFLs) which emitting in the spectral region of 1010 nm ~ 1050 nm, have drawn more and more attention especially after the proposition of tandem pump fiber lasers. The S-band laser plays an important role as the pump in a tandem pumping scheme.
