Tsunami Figure 6-18: Pr1/Pr4 prisms showing placement of beam. Refer to Table 6-4 for the value of x. 17. Adjust MI, then M1 0, for maximum output power (peak the laser). Refer to chapter 7, "Operation: Optimizing Laser Output." 18. Install the tuning slit assembly. a. Close the shutter. WARNING To avoid damaging nearby optics when installing the slit, carefully move it into place and use your hand to support it while you tighten the mounting setscrew. b. Place the tuning slit assembly into the laser head and onto the micrometer shaft. Refer to Figure 6-10. c. Rotate the slit width adjustment screw until the dowel pin on the mating shaft can slide into the slot. d. Seat the slit assembly against the micrometer stop. e. Tighten the setscrew that holds the slit assembly on the shaft. f. Open the shutter. g. Venfy the slit opening is in the beam path. h. Adjust MI and M10 for maximum output power. 19. Tune the slit for the desired wavelength. -- "- Refer to chapter 7, "Operation: Selecting Wavelength, fs Configuration." 20. If changing from < 900 to > 900 nm, or vice versa, you need to change the photodiode pc board. Refer to "Aligning the Photodiode PC Board" earlier in this chapter. 21. Re-enable the AOM by pressing the STATUS mode locker enable button. 22. Mode lock the Tsunami laser.
Alignment Refer to chapter 7, "Operation: Mode Locking the Laser." 23. Adjust MI and MI0 for maximum output power. Ensure that ion laser pump power is at optimum setting. Converting Between Overlapping Optics Sets DANGER: LASER RADIATION This procedure requires you to replace optics while using the laser at high power. For safety, close the pump laser shutter every time you change an optic, and only open it during alignment. Protect yourself with appropriate eyewear at all times. CA UTlON Always use clean finger cots or powderless gloves when handling optics. WA RNlNG 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. To change between overlapping wavelength ranges, follow the same procedure outlined under "Converting Between Non-overlapping Optics Sets" above. However, note the following: 1. Before making the conversion, tune the laser to a region overlapped by the two optic sets, and optimize laser output. Refer to the tuning curves in chapter 3. 2. During each adjustment following the installation of an optic, instead of only verifying that the cross-shaped fluorescent image is visible on the white card, adjust the optic to get the system lasing. Once lasing, adjust just that optic for optimum output. Do this for all optics except mirror MS. M3 is changed last. 3. When M3 is replaced, place a white card in front of M5, and adjust P2 to overlap the two fluorescent ovals so they form the cross-shaped image. Then remove the white card and adjust M3 until the system lases. 4. Verify the laser beam is centered on MI to M5, as well as MI0. Adjust photodiode pc board if required (refer to earlier section on pc board alignment).
