Abstract Here, we present a fiber-optic dispersive wave generator for highly-efficient, wavelength-tunable ultrashort pulse generation, enabling multicolor deep-tissue two-photon imaging of neuronal and vascular structures in labeled mouse brain. Guided by comprehensive numerical simulations, a compact Yb:fiber laser-driven system is constructed that utilizes precisely parameter- and phase-matching-controlled dispersive wave generation in a photonic crystal fiber.

Abstract In this work, we investigate an approach to scale up the output pulse energy in an all-polarization-maintaining 17.3 MHz Yb-doped fiber oscillator via implementation of a 25 µm core-diameter large-mode-area fiber. The artificial saturable absorber is based on a Kerr-type linear self-stabilized fiber interferometer, enabling non-linear polarization rotation in polarization-maintaining fibers.
