Rodolfo | Laser | Laser for H-like 209Bi | I have changed the dye to Rhodamin 610 + Rhodamin
640. The Cobra wavelength can be tuned now
from 600 to 630 nm.

Simon, Christopher, Kristian, Sebastian | Laser | Labview VI checkups | The lower limit (to position) of the Cobra
control VI has to be one increment smaller.
This means for moving from 601,95 to 601,74 |
