A high-brightness ultrabroadband supercontinuum white laser has attracted more and more attention in physics, chemistry, biology, materials science, and other disciplines of science and technology. Over the past decades, many different approaches have been developed for supercontinuum white laser generation.
Most of them utilize various third-order nonlinear effects like self-phase modulation occurring within microstructured photonic crystal fibers or homogeneous plates, or noble gas-filled hollow-core fibers. However, the quality of these supercontinuum sources has been subject to some limitations, such as small pulse energy at nanojoule level and request of complicated dispersion engineering.
Frankly speaking, it has become a great challenge to resolve these bad limitations existing in both 2nd-NL and 3rd-NL regimes and make the best of both worlds for producing a full-spectrum supercontinuum laser with spectral coverage from UV to mid-IR range.
