ULTRA-BROADBAND FEW-CYCLE PULSE OSCILLATORS Rainbow™ is an ultrafast few-cycle pulse Ti:Sapphire oscillator family using Dispersive Mirror (DM) technology. DMs are specifically designed for broadband intracavity group delay dispersion compensation. The Rainbow Advantage • GreenAlign™ stabilization and ease of operation • Extremely broad spectrum • Low noise • Ultrashort pulses • Compact footprint • Excellent long term output stability • Temperature stabilized base plate When paired with CEP4, Femtolasers’ feed-forward Carrier Envelope Phase (CEP) stabilization, the Rainbow generates the shortest, CE phase-stabilized optical pulses commercially available with unprecedented quality, stability and reproducibility. DM systems constitute the ideal solution for a wide range of scientific, industrial and medical applications. The Rainbow series now includes advanced models with multiple outputs. The Rainbow CEP model offers two CEP-stabilized simultaneous outputs. All CEP-stabilized models can be equipped with a switch to offer full power output without CEP-stabilization. An optional 1030 nm output allows direct optical seeding of Yb-based lasers which are typically used in OPCPA chains. Ultrashort Pulses Intracavity high order dispersion can be eliminated to an extent that high quality, near bandwidth-limited sub-6 fs pulses can be generated from a Ti:Sapphire oscillator. An Extra Cavity Dispersion Control (ECDC) unit provides precise dispersion control outside the oscillator to transmit pulses with these extraordinary parameters to your target. Stability and Reproducibility Intracavity dispersion insensitivity to cavity alignment results in excellent reproducibility and day-to-day performance. The innovative and patented cavity design features the lowest energy noise and timing jitter demonstrated in the sub-6 fs regime to date. Applications • Amplifier and OPCPA seeding • THz spectroscopy and imaging • Optical coherence tomography • Ultrafast spectroscopy • Pump-probe measurements • Nonlinear optics • Multiplex CARS • Surface enhanced HHG • Nano optics
