Tsunami Unless you are certain the new optics are clean, clean each one as it is placed in the laser. Refer to chapter 9, "Maintenance," for cleaning procedures. To observe the intracavity fluorescence throughout the following procedure, place a white card about 10 cm outside the laser output port.

It is important the steps below be followed in sequence and that each is completed before starting the next step. The laser will not lase until every optic is replaced with optics from a single set. If you cannot get the system to lase and you feel the cavity is misaligned, install the standard optics set (which is easier to get lasing) and refer to "Cavity Alignmenty' earlier in this chapter to check the alignment of the system. Once the system lases, repeat this procedure. If the beam is severely misaligned, realign the cavity. Refer to "Cavity Alignment" earlier in this chapter. WARNING Tsunami should meet specified power for the installed optic set before changing optic sets. Refer to chapter 7, "Operation: System Start-up," and to the specifications listed in Table 3-1 and Table 3-2. 1. Turn off the AOM by pressing the STATUS mode locker enable button on the Model 3955. 2. Verify the beam is centered on MI, M4, M5, and Mlo. Perform step 3 if your laser is configured for fs operation, otherwise skip to step 6. 3. Carefully remove the slit assembly (if present). a. Close the shutter. b. Loosen the setscrew that holds the slit assembly to the spindle of the micrometer (Figure 6-9), then slide the assembly down and off the micrometer shaft. WARNING Support the slit assembly with your hand when loosening the setscrew to prevent it from falling off and damaging the optics below. c. Open the shutter. d. Using the prism dispersion compensation control, adjust the prism Pr2/Pr3 assembly so the beam is at least 5 mm from the apex. 4. Replace the high reflector at MI. Unscrew the high reflector holder, replace the high reflector in the holder with the appropriate optic for the chosen wavelength, and screw the holder back in.
