Spectra-Physics Tsunami - Table 3-3: Tsunami Femtosecond Performance When Pumped by a Millennia Laser

Tsunami Mode-Locked Ti:sapphire Laser
3-14
1
Specifications subject to change without notice and only apply when the Tsunami is pumped by a Spectra-Physics Mil-
lennia X or V diode-pumped CW laser.
2
Specifications apply to operation at the wavelength noted.
3
A sech
2
pulse shape (0.65 deconvolution factor) is used to determine the pulse width as measured with a Spectra-
Physics Model 409 autocorrelator.
4
Laser operation is only specified at a nominal 80 MHz repetition rate.
5
Rms, measured in a 10 Hz to 2 MHz bandwidth.
6
Percent power drift in any 2-hour period with less than a ±1°C temperature change after a 1-hour warm-up.
7
Pulse widths below 50 fs and between 150 fs and 1 ps are also available. Contact your local Spectra-Physics represen-
tative for more details.
