This morning, we took advantage of having all the electronics of the injection down (for the works that are currently done in the EER) to proceed with the replacement of the laser diodes of the slave laser.
Laser diodes have a limited life time, by changing them we are increasing the reliability on the slave laser functionning for the coming runs.
The laser diode PSL-FOPT-1608-03 has been replaced by the PSL-FOPT-1608-05 while the PSL-FOPT-1608-04 has been replaced by the PSL-FOPT-1401-01 (see the attached pictures).
When the works in the EER will be finished, we will restart everything and set the pumping current of the diodes to have the same output power than the old ones.
