Interval excitation type laser source

Abstract

The invention relates to an interval excitation type laser source which comprises an initial signal source, a resonance detection signal source, a power amplifier, a microprocessor and a laser. A signal of the initial signal source is output to the resonance detection signal source; a signal of the resonance detection signal source is output to the power amplifier; an output end of the power amplifier is connected to the laser; the microprocessor is applicable to the implementation of real-time light intensity power detection on the laser and control and feedback on the resonance detection signal source and the power amplifier according to a power detection result; and the microprocessor also carries out compensation regulation on the initial signal source. The interval excitation type laser source disclosed by the invention can enable an output frequency of the laser to be more accurate and enable output power of the laser to be more stable.

Description

technical field [0001] The invention relates to the technical field of atomic frequency standards, in particular to a spaced excitation laser source. Background technique [0002] The atomic frequency standard is realized by using a quantum interference phenomenon produced by the interaction between atoms and coherent laser light. It is also the only atomic frequency standard that can be miniaturized in principle. The working mode of continuous laser and atomic interaction is adopted, but the current existing ones use acousto-optic modulator (AOM) as an optical switch to generate pulsed laser. Due to the large size and high power consumption of AOM, the atomic frequency standard is limited to miniaturization and Development in the direction of low-power atomic frequency standards. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a spaced excitation laser source which uses digital technology to realize the periodi...
