The hollow core fiber compressor spectrally broadens high-energy femtosecond input pulses by nonlinear

interactionwith a noble gas of adjustable gas pressure inside a hollow fiber. Ultra-broadband chirped 

mirrors compress the white light pulses after the fiber, and the increased spectral width supports shorter 

pulse durations than the original input. Effectively, the device compresses the input pulses temporally by 

increasing their spectral bandwidth. Our device draws on extensive expertise in the generation of intense

few-cycle pulses for attosecond research and combines high transmission with unique ultra-broadband 

compression. Besides pulse compression the extremely broadband fiber output addresses also state-of-

the-art spectroscopy experiments.

Fiber Output Spectrum

The extremely broadband fiber output spectrum 

(before the spectral mirror shaping) facilitates 

spectroscopy experiments from 400 nm up to the

NIR at 1200 nm.

Ultra-broadband Chirped Mirror Technology:

Our double-angle chirped mirrors are a key component of the 

hollow core fiber compressor. Building onextensive 

experience in ultrafast coating design these mirrors provide 

unprecedented broadband compression with the proven 

capability to produce pulses with <4 fs duration. Custom 

solutions for specific spectral coverage and selection are 

available.
