Ti: SAPPHIRE ULTRAFAST OSCILLATORS
- High-performance optics (HP models) offer the broadest tuning range of 700 nm – >1080 nm
- High peak power of >337 kW efficiently drives non-linear optical processes
- Regenerative mode locking for long-term stability
- Stable mode locking at the edges of tuning range
The Tsunami ultrafast Ti:Sapphire oscillator series provides unmatched flexibility and capability. The Tsunami series’ regenerative mode-locking mechanism sustains transform limited pulses, even during perturbation of the cavity, and enables coverage of a broad range of wavelengths with short femtosecond pulses out to very long picosecond pulses.
The Tsunami series contains the flexibility to have both femtosecond and picosecond pulses on the same platform with the 3960 series, a femtosecond only version with the 3941, and picosecond only with the 3950 series. The Tsunami series can be pumped with a Millennia eV in powers of 5, 10 or 15 watts so that the laser output can match the required amount of energy for each experiment.
The superior design of the Tsunami prism dispersion compensation enables short, transform-limited pulses. The unique l-track prism movement enables excellent beam pointing as the laser is tuned. The use of slits for wavelength selection in femtosecond operation, combined with advanced dispersion compensation allows wide pulse duration adjustment over the femtosecond range from <60 femtoseconds to >900 femtoseconds. The Tsunami laser can then be easily converted to picosecond mode to cover from less than 2 picoseconds to greater than 100 picoseconds with use of the appropriate GTI.
The Tsunami laser pulses can be synchronized to other lasers or laboratory equipment with the optional Lok-to-Clock® accessory that actively stabilizes cavity length. Lok-to-Clock electronics also provide high-speed input that can be used to slave the laser to a reference pulse train from another laser.
Short Pulse Width
The short pulse Tsunami systems use the latest generation of high-performance optics to allow >65 nm of bandwidth for <30 fs in pulse width. When pumped by the Millennia eV 10, the Tsunami 3941-30-X1S typically achieves >800 mW of average power with <350 kW of peak power.
When the Tsunami oscillator is combined with the broad range of Spectra-Physics harmonic generators and optical parametric oscillators, such as the Inspire™ OPO, wavelength coverage spans from 210 nm – 5 μm. Pulse picking can offer repetition rate flexibility from single shot to 8 MHz, while still providing enough pulse energy for demanding fluorescence lifetime applications.
