…differentially-pumped hollow core fiber, pressurized with
either neon or helium gas. The pulse energy from the Astrella is controlled over the range 0-7 mJ with a waveplatepolarizer combination (not shown). The spectrally-broadened output from the hollow core fiber is re-collimated by a

light continuum with hollow core fibers,
initially called "holey fibers," but now
often called photonic crystal fibers. Our
group was then in a bit of a race with
the team of John Hall in Boulder to get
our hands on this type of fiber in order
to generate these…

…generation
Supercontinuum light sources combine an ultrafast laser (usually a fiber laser) with an optical fiber, which could be a microstructured or photonic-crystal fiber (PCF), with a very small
core diameter to intentionally cause nonlinear optical effects
that result in a…

…To this end, Kambhampati and graduate student Hélène Seiler decided to
investigate the use of a hollow core fiber to generate the requisite white light continuum.
A hollow core fiber is a narrow glass or quartz capillary that acts as a waveguide. In this case, it is
filled with an…

…routinely, corresponding to around 10 cycles of the electric field for visible light. And with novel pulse compression schemes, such as using hollow core fibers, even "single cycle" pulses in the 3- to 5-fs range can be achieved. Because of the high intensity of the light that can be reached for…
