sentative.
Options
Ultrashort (< 50 fs) Pulse Option
All Tsunami systems with a serial number suffix “G” can be upgraded to
provide output pulses of < 50 fs. The ultrashort pulse option is available
only for the standard wavelength region with a specification of < 50 fs at
> 1.0 W at 790 nm for a Millennia Xs pump source. The upgrade part num-
ber is 0449-1050S.
Ultrashort (< 35 fs) Pulse Option
For this configuration, the pulse width of the Tsunami is specified at < 35 fs
over a tuning range from 780 to 820 nm. With a Millennia Vs pump laser,
output energies at 800 nm exceed 400 mW.
Because major changes to the cavity configuration are required, this
upgrade is only available as a factory option.
Broad Femtosecond Pulse Option
The broad fs pulse option provides 150 fs to 1 ps output pulse capability.
The option comprises special GTIs that are used for dispersion compensa-
tion in conjunction with the prism sequence.
Broad Picosecond Pulse Option
The broad ps pulse option delivers transform limited 10 to 80 ps pulses. Power
is specified at 1.5 W at 30 and 60 ps for a Millennia Xs pump source. The
broad pulse option uses special GTIs and a 2 or 3-plate birefringent filter.
76 MHz Option
The Tsunami cavity can optionally operate at 76 to 83 MHz in addition to
the standard 80 and 82 MHz repetition rates. This is a factory option. Con-
tact your Spectra-Physics service representative for more information.
