Managed to capture some data of the frequency-stabilised #laser although the save file didn't have enough decimal places - it was just "396.84690" nm after the first minute.  Counting pixels on the graph allowed me to determine a roughly 0.000009nm or 17MHz full range.  That's good because the Ca+ ion line I'm trying to hit for Doppler cooling has a natural line width of 22MHz.  #physics #accelerators<p><a href='posts/202611/post-20261110-202758-a.png'><img src='posts/202611/post-20261110-202758-a.png' loading='lazy' /></a></p>
