780nm laser frequency locking module
Cold atom experiments with Rb need lasers with specific frequency and Erbium group launches different frequency locking schedules for 780nm laser. We built up an all-fiber-connected frequency locking module with an integrated optical system and other optical fiber devices. This module can offer stable SAS or MTS signal and together with our laser controller Preci-Lock, frequency locking with good long-term stability is realized. The frequency difference between two lasers should keep to a constant value in some cold atom experiments. For 87Rb atom gravimeter, the frequency difference of cooling laser and repumping laser should be about 6.6GHz and for the two Raman lasers the value is 6.834GHz. PreciLasers has launched a specialized laser controller Preci-Beat for offset frequency locking in the range from 50MHz to 8GHz with beat frequency/phase locking technique.
