Spectra-Physics Tsunami - Tsunami Laser Specifications

Tsunami Mode-Locked Ti:sapphire Laser
3-12
Specifications
Table 3-3 lists performance specifications for fs configurations pumped
with a Millennia-series laser. Table 3-4 lists performance specifications for
ps configurations pumped with a Millennia-series laser. Table 3-5 lists the
electrical, mechanical and physical specifications for the Tsunami laser.
Table 3-6 lists the environmental specifications. Specifications for the
optional Lok-to-Clock system are found in Table 3-7. Figure 3-5 through
Figure 3-10 earlier in this chapter show the tuning curves for typical fs and
ps systems, respectively.
