Bandwidth limited 92 fs 10 µJ pulses are generated using an adaptive fiber Bragg grating stretcher for group delay and an adjustable Lyot filter for bandwidth control, and compressed to 12 fs in a hollow-core fiber.
We optimize the intensity of six wavelengths in a supercontinuum by tuning the dispersion of a chirped fiber Bragg grating. The phase stability between wavelengths exceeds that of most optical clocks.
We demonstrate spectral self-compression in a hollow-core gas-filled photonic crystal fiber for the generation of high energy ps pulses with limited bandwidths.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
