Tsunami Figure 6-9: The Slit Control g. For a fs-configured laser, adjust M5 SO the fluorescent spots go through Prl and the other three prisms and are displayed on the white card. An ir viewer is required to view these spots. For a ps-configured laser, adjust M5 to guide the fluorescent spots directly onto the card. CA UTION Fs-configured laser: Do not place the card between optical components from M6 to M9. The refraction of fluorescence through the prisms causes the spots to spread in the vertical plane and, thus, are not representative of the laser beam path. DO NOT adjust these components. h. Remove the white card and place it about 10 cm outside the output window.
Alignment i. Adjust M5 to direct the fluorescent spots through the AOM, through MIo, and onto the card. The spots should be centered in the background scatter that is shaped by the AOM and Mlo. An ir viewer may be required in order to view the small, crossshaped image on the white card (Figure 6-7) centered in the background scatter. If the image is absent, it may be blocked by one or both of these components. Place another white card between the AOM and MI0 and, using it as a knife edge (slowly moving it into the fluorescent spots), detect the position of the beam relative to the two components and properly center it. j. Remove the white card. CA UTlON DO NOTremove or adjust mirrors M6, M7, M8, or M9, or the prisms in a femtosecond Tsunami laser (Figure 6-10). These optics are prealigned at the factory and are not to be disturbed unless specifically told to do so elsewhere in this manual. A service call may be required if disturbed. 16. Align Mlo. a. Place a power meter in the Tsunami output beam path as a beam block. Figure 6-10: Four PrismLFour Mirror Section of Laser Cavity
