Tsunami Mode-Locked Ti:sapphire Laser

Figure 8-6: Synchronization of two Lok-to-Clock Tsunami Lasers
1. Adjust each Tsunami laser for optimum performance at the desired
wavelengths.
2. With each Model 3930 unlocked (there are no illuminated segments in
either
STATUS display), place a photodiode (e.g., an Electro Technol-
ogy
ET2000) at the source of the experiment.
3. Adjust the optical alignment so that the pulse train for each Tsunami
laser can be identified.
4. Set up and lock Tsunami “A” as outlined in “Operation Notes” above.
5. Repeat Step 4 for Tsunami “B.”
The oscilloscope display should now show two pulse trains with a fixed
delay. The pulse trains are now synchronized but are probably not over-
lapped in time.
6. Verify the time between the pulse trains can be varied by using the
coarse
TIMING control.
