  1. Laser operation is specified at a nominal repetition rate of 80 MHz.
  2. Specification represents rma noise measured in a 10 Hz to 2 MHz bandwidth.
  3. Percent power drift in any two-hour period with <±1°C temperature change after a one-hour warm up.
  4. 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.


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.


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 Tsunami laser pulses can be synchronized to other lasers or laboratory equipment with the optional Lok-to-Clock® accessory. Lok-to-Clock actively stabilizes the cavity length to an internal reference clock or can be used to slave the laser to a reference pulse train from another source.

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.


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.
