Footnotes:
- Due to our continuous product improvement program, specifications may change without notice. Specifications only apply when the specific Tsunami model is pumped by a Spectra-Physics Millennia eV 15 W, 10 W or 5 W solid state laser and the entire Tsunami Environmental Package is installed.
- Specification applies to 800 nm only.
- A sech2 pulse shape (0.65 deconvolution factor) is used to determine the pulse width as measured with a Newport PulseScout®.
- The Tsunami model 3960 requires additional components to run in picosecond mode (sold separately).
- Tsunami is a Class IV - High-Power Laser, whose beam is, by definition, a safety and fire hazard. Take precautions to prevent exposure to direct and reflected beams. Diffuse as well as specular reflections can cause severe skin or eye damage.

Features
Superior Design
The superior design of the Tsunami prism dispersion compensation enables short, transform-limited pulses. The unique λ-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.
Flexibility
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.
Short Pulse Width
The short pulse Tsunami systems use high-performance optics to allow >65 nm of bandwidth to produce <30 fs pulses. The Tsunami 3941-30-X1S typically achieves >800 mW of average power with >350 kW of peak power.
Expansion
The Tsunami oscillator can be combined with Spectra-Physics harmonic generators and optical parametric oscillators, such as the Inspire™ OPO. Optional pulse picking can be added to adjust the repetition rate from single shot to 8 MHz, while still providing enough pulse energy for demanding fluorescence lifetime applications.
Compatible Power Sensors
To verify and analyze the output power of your Tsunami laser, we recommend the Ophir 10A (7Z02637) or 3A (7Z02621) thermal power sensor and Centauri laser power meter. Additional information on this laser measurement equipment can be found on the ophiropt.com website. Other Ophir sensors and meters may also be suitable for the Tsunami, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
