As the result of long-lasting optimization at the Max-Planck Institute for Quantum Optics (Garching, Germany) our hollow core fiber compressor combines optimum fiber coupling in an ultra-stable setup with our unique PC70 chirped mirrors for best available pulse compression results, making it a versatile tool for applications ranging from attosecond pulse generation to OPCPA seeding and 2D electronic spectroscopy.
The hollow core fiber compressor is ideal to generate intense few-cycle pulses with ultrabroad bandwidth from the output of Ti:Sa amplifiers. The output pulse duration of laser amplifiers is limited by gain narrowing to about 20 fs, and shorter pulses can only be reached with additional spectral broadening. Our hollow core fiber compressor couples the laser output with high efficiency into a noble-gas filled glas capillary, where nonlinear interaction broadens the input pulses. With our optimized design extreme spectral broadening to a coverage of up to 270-1000 nm has been shown. Pulses after the fiber are compressed with our PC70 ultra-broadband chirped mirrors featuring our proprietary double-angle technology for the best available pulse-compression performance. As extensions to the hollow core fiber compressor we can provide an input beam stabilization module, a gas and vacuum handling system, and variable GDD management.
