Highly-efficient perturbative Raman shifting by engineering the nonlinear temporal response
Yi-Hao Chen, Wenchao Wang, Shaodong Hou +4
Raman scattering underlies a broad range of spectroscopic and light-generation techniques, yet its conventional description, based on the Raman gain spectrum, accurately describes…
Partial parabolic amplification in rare-earth-doped optical fiber
Wenchao Wang, Yi-Hao Chen, Frank Wise
Nonlinear amplification is a powerful technique for generating ultrashort laser pulses with high peak power in fiber systems. However, the diversity of nonlinear amplification appr…
Analysis and control of Raman phonon dynamics for enhanced optical frequency conversion
Yi-Hao Chen, Frank Wise
Raman phonons are quantized molecular motions that arise from the inelastic scattering of light and mediate a wide range of spectroscopic and nonlinear optical phenomena. These can…
Raman-enhanced spectral compression of high-energy femtosecond laser pulses in molecular gases
Zegui Wang, Yi-Hao Chen, Yunlong Mo +4
Nonlinear pulse propagation in gas-filled waveguides has attracted substantial attention over the past decade, and a variety of capabilities have been reported. However, there is n…
Tutorial of Fourier and Hankel transforms for ultrafast optics
Yi-Hao Chen
This tutorial is designed to clarify a few misconceptions in the field of ultrafast optics. (1) Analytic signal that underlies the complex-conjugate decomposition of the field is d…
A simple accurate way to model noise-seeded ultrafast nonlinear processes
Yi-Hao Chen, Frank Wise
Noise can play an important role in nonlinear pulse propagation. It is not only the origin of fluctuations in supercontinuum but can also determine the generated signal amplitude a…
Efficient, broadly-tunable source of megawatt pulses for multiphoton microscopy based on self-phase modulation in argon-filled hollow-core fiber
Yishai Eisenberg, Wenchao Wang, Shitong Zhao +13
An exciting recent development for deep-tissue imaging with cellular resolution is three-photon fluorescence microscopy (3PM) with excitation at long wavelengths (1300 and 1700 nm)…
