Description

Technical field [0001] The present invention belongs to the field of laser technology, and more particularly to a frequency-locked single-band semiconductor laser device. Background technique [0002] Quantum precision measurement technology has verified its high-precision sensitive measurement ability. Currently, it is moving towards improvement accuracy and engineering, which has an extremely important role in the construction of high-precision autonomous navigation capabilities. . [0003] Quantum precision measurement is dependent on single-frequency laser, and single-frequency laser needs to be stably locked in the vicinity of super-fine lines at the atom. Commercial single-frequency laser devices are basically not integrated with steady frequency, and the implementation of the steady frequency function is increasing to increase the volume of the volume. This embodiment is not conducive to the deviceification and engineering of single-frequency lasers, hindering quantum prec...
