Coherent Whitepaper - Astrella Tisch Sphere FINAL.pdf

…Optimized Hollow Fiber Compressor In this demonstration experiment, the output pulses from an Astrella amplifier (35 fs pulse width and 1 kHz repetition rate) were focused into a HFC. This takes advantage of the spectral broadening caused by self-phase modulation (SPM) in a hollow fiber containing…

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

…Professor Tisch explains the context of these first results, "Most hollow fiber users are injecting around 1 mJ into their fibers. This is the typical energy limit if differential pumping is not employed, i.e., if the hollow fiber is filled with a uniform gas pressure. Only a small number of…

Lucent Technologies demonstrated the ability to efficiently generate a white 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…
