UltraFast - SAVANNA-HP
High power stretched flexible hollow core fiber pulse compresso


High power stretched flexible hollow core fiber pulse compressor

The SAVANNA-HP is the result of a collaboration between UltraFast Innovations and the Institute for Nanophotonics in Göttingen IFNANO. The stretched flexible hollow core fiber (SF-HCF) compressor spectrally broadens high-energy femtosecond input pulses by nonlinear interaction with a noble gas of adjustable gas pressure inside a hollow fiber and subsequently compresses the pulse using chirped mirror technology from UltraFast Innovations. The state of the art SF-HCF technique from IFNANO allows nearly ideal wave guiding reducing the losses to a minimum and allows accumulation of self-phase modulation over an interaction length of up to 8 m. The incoupling is protected by a high power shield allowing extreme input parameters of few tens of mJ pulses and an average power of up to 20 W (with active cooling up to several hundred Watts). Combining the SF-HCFs from IFNANO and our chirped mirror compression, we provide an unmatched compression unit for today's state of the art lasers.
