I checked the BS oplev laser this morning and sure enough, as per Keita's aLOG here, the laser was going bad and in need of replacement. I watched the current monitor on the laser with a voltmeter (the monitor outputs a voltage) and ever 70'ish seconds it would drop from the set 0.760 V to 0.743 V. This laser was replaced with one from the EE lab fresh off an install of a DC to DC convertor board. This laser and its temporary DC power supply were installed between BSC2 and BSC3, on the East side. I tried to hide the power supply as much as I could to protect from accidental damage but it is large, so for anyone working in that area, please watch your feet. After installation I watched the current monitor and didn't see any drops as was seen with the previous laser.
