The FEMTOPOWER™ compact™ is a series of ultrafast Ti:Sapphire multipass amplifier using a sealed vacuum chamber system for the amplifier crystal and Dispersive Mirror (DM) technology for dispersion compensation. The system generates down to sub-25 fs, high-energy optical pulses with contrast ratios better than 1:109 or phase stabilized, high-energy optical pulses (CEP version) commercially available with unprecedented quality, stability, and reproducibility. Combined with the hollow fiber compressor KALEIDOSCOPE™ even sub-7 fs pulses with energies in the 0.8 mJ regime are easily available to the user. The compact multipass system is the optimum choice for a wide range of scientific, industrial, and medical applications.
