keyword=Laser No3. not working properlyWhen I checked the Laser absorption spectrum I noticed that something
is wrong with the lasers, because its amplitude was smaller than it should be (3/4). I checked the laser controls and noticed that temperature of the laser 3 is fluctuating for a degree although it
should be pretty constant. The power of the laser seemed to be constat. I have called Yi and he explained to me that until temperature changes are within one degree it should be fine. However,
we should monitor this temperature carefuly. After I stopped talking
to Yi the absorption spectrum almost came back to its original value.
