Richard cleaned the fiber this morning at the Y end patch panel, and after that we had 18-19uW at the table feed-through and I measured 14uW with the power meter in air on the table. After realigning for the swapped beamsplitter, (and re-aligning the power monitor PD) the beatnote was -38dBm, around -20 dBm after the amplifier. A plot of the OLG will follow, but the main message is that the ALS PLL is working. It has been locked for almost hours now, based on looking at the striptool of the beat frequency and the control signals. The settings are: cg -15, fg 22, common compensation on, slow ugf set to -0.015Hz and slow pole set to 0.0001 Hz. The beatnote frequency has glitches that are not present in the channel for the VCO frequency, where the signal level is much higher. It might be easier to write an autolocker if we could get rid of those glitches, perhaps by amplifying the signal.
