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.
