Tsunami
Aligning the Tsunami Laser Head to the Pump Beam
-
WARNING
-
Verify the pump laser is set to minimum current before proceeding with
the next step. A high-power beam will damage the Ti:sapphire crystal
when the chiller is not hooked up and operating.
1. Open the pump laser shutter.
2. Align the Tsunami laser head to the input pump beam.
a. Open the Tsunami interlock shutter by raising the red-capped
lever to the vertical override position.
DANGER: LASER RADIATION
Tsunami is a Class IV High Power Laser. Bypassing the safety interlock
shutter might expose the user to hazardous radiation. Always wear
proper eye protection and follow the safety precautions in chapter 2,
"Laser Safety."
DANGER
Be aware that during steps b and c invisible radiation could emit from
the output of the Tsunami laser, as well as from various optical components.
--
b. Move the Tsunami until the pump beam passes through the center
of the input window and strikes the center of pump mirror PI
(refer to Figure 4-3).
The laser head should now appear to be aligned parallel to the
beam.
c. Close the pump laser shutter.
d. Secure the Tsunami laser head to the table with the three foot
clamps provided.
The clamps slide over the lower portion of each foot.
e. Verify the height adjust locking nuts on the feet are tight.
This completes the installation of the Tsunami laser head.
