The development of fiber amplifier schemes and the study of the pulse regimes were carried out as part of the state assignment of the IAE SB RAS ‘‘Development of Elements and Study of the Characteristics of Laser and Sensor Systems Based on Structured Wave Light Guides, Microresonators, and Hybrid Schemes’’ (project no. FWNG-2024-0015). The design and fabrication of Bi-doped fibers were supported by the Russian Science Foundation (grant no. 22-19-00708-P). We also thank the multiple-access center ‘‘High-Resolution Spectroscopy of Gases and Condensed Matters’’ at IAE SB RAS for the use of its equipment.

N2 - We compare three all-fiber amplifier schemes for highly-chirped pulses near 1.3 micron: one based on stimulated Raman scattering in a standard passive fiber, another utilizing the active centers of a Bi-doped fiber, and a third combining both approaches in a hybrid configuration. Amplification in the Bi-doped fiber provides a higher net gain than Raman amplification but introduces spectral distortions of the pulses. We have shown that spectrally uniform amplification simultaneously with high gain can only be achieved in the hybrid scheme, resulting in a 19-fold net gain, a 25 nJ output pulse energy, and a compressed pulse duration of 650 fs. The resulting source holds great potential for application in deep-tissue multiphoton microscopy.
