Tsunami b. Move the stage by hand and set it so the vertical edge facing the rod is placed at the third reference mark from the end of the slide. There are reference marks scribed on the vertical surface of the nonrnoveable dovetail. They are very fine and can be hard to see. c. Tighten the setscrew. 10. Set the initial position for cavity focusing mirror M2 by adjusting the M2 micrometer for "7" on the gradation scale (Figure 6-5). 1 1. Align pump beam steering mirror PI. a. Venfy the pump laser is set for minimum current. b. Open the pump laser and Tsunami shutters. c. Center the pump beam on Pl (Figure 6-6) using the vertical and horizontal adjustments on the routing mirrors. d. Adjust PI vertically and horizontally to center the pump beam on P2. 12.

Alignment opposite this hole. PI Pump Steering Mirror P2 Pump Focusing Mirror Figure 6-6: Pump Mirrors PI and P2 Vertically and horizontally adjust the tilt of P2 to direct the pump beam through M3 and the rod, and center the emerging beam on M2 (Figure 6-5 and Figure 6-6). Centering the beam on the intracavity surfaces of M2 and M3 is critical for proper mode overlap in the rod. If the beam is centered on M2 but not on M3, walk the pump beam on P2, adjusting both PA and P2, until proper alignment is achieved. 13. Align cavity focus mirror M2. Adjust M2 vertically and horizontally to direct the small amount of pump light reflected from M2 though the center of MI. 14. Adjust the focus of M2 and MS. Use an ir viewer and white card for the following steps. a. Place the white card in front of M4. b. Increase the pump laser to nominal power. c. Adjust M3 vertically and horizontally to center the image on M4.
