Light from MP023

Light is picked off from the K repump line in MP023, after it has been locked to the ³⁹K F=2 -> ²P_3/2 (unresolved), then shifted an additional ~-308MHz by AOM1 and AOM2:

AOM1	1x(-116MHz)
AOM2	2x(-96MHz)
Total	-308MHz

note: values on MP023 Laser Settings may be a little different.
