ULTRASHORT PULSE MULTIPASS AMPLIFIER WITH OPTIONAL CEP STABILIZATION The Femtopower Advantage • Shortest pulses • Highest pulse-to-ASE contrast • Best CEP stabilization The Femtopower™ family of ultrafast multipass Ti:Sapphire amplifiers is designed as the optimal light source for the most demanding applications. Femtopower is the only amplifier proven to consistently provide outstanding CEP stability and highest pulse-to-ASE contrast in a reliable and user-friendly configuration over the longest period of time. Femtopower incorporates Femtolasers‘ unique patented key technologies, and can be seeded by the state-of-the art Rainbow™ 2 CEP4 oscillator to generate CEPstable multi-mJ pulses. When used in conjunction with the Kaleidoscope™ to reach sub-7 fs pulse durations, the Femtopower is the ultimate commercial light source for attoscience. Systems not requiring CEP stabilization are seeded by the successful Element™ PRO oscillator. The sub-20 fs provided by the Femtopower PRO set a new benchmark in terms of spectral bandwidth and pulse duration. Applications • Attoscience • High harmonics and X-ray generation • Ultrafast spectroscopy • Femtochemistry • Front-end for TW and PW systems • Coherent THz generation • Materials processing • OPCPA seeding and pumping • OPA pumping Unequaled pulse quality is ensured by the Dispersive Mirror based seeder and accurate quantitative dispersion management in the amplifier. This leads to cleanest pulses and highest pulse-to-ASE contrast ratio on the market. Femtopower amplifiers are equipped with Vactec™ or Vacool™, powerful crystal cooling systems dramatically reducing thermal lens effects while avoiding vibrations. The result is an excellent beam profile and a fast cool down time without adverse effects on the CE-Phase stability.
