Info

Tsunami relays that are used to disable the drive signal when the limit is reached in each direction. Provide an "Off" switch as shown to insure there is no - creep after M1 has been properly positioned. Make all the appropriate connections to ground. Remember to provide the + 5 Vdc and the 220 G pull-up resistors as shown in Figure 8-10 to drive the optical side of the limit switches, and the 10 K pull-up resistors for the limit switch output signals. The + 5 Vdc in Figure 8-10 is the same + 5 Vdc that should be used to drive the relays in Figure 8- 11. The limit switches restrict the total range of coarse travel to about 1.25 cm. This corresponds to a change in laser repetition rate of over 500 kHz. Note that when you tune a fs Tsunami laser over a given optics set, as the dispersion is adjusted for optimum pulse width performance, the repetition rate (cavity length) is changed by over 300 H z. The coarse control allows you to maintain a reasonably constant cavity length as the wavelength is tuned.
