Abstract

A Pound-Drever-Hall frequency stabilizing system of a dual-cavity dual-frequency solid laser device comprises the dual-cavity dual-frequency solid laser device, two independent heterodyne interferometer systems, two frequency regulators and an F-P (Fabry-Perot) optical resonant cavity. The optical resonant cavity is used as frequency stabilizing reference, the two independent heterodyne interferometer systems are used for detection to obtain two channels of error signals, the two frequency regulators are driven, and two working frequencies of the dual-cavity dual-frequency solid laser device are simultaneously locked at two resonance frequencies of the F-P optical resonant cavity. The F-P optical resonant cavity is used as the frequency stabilizing reference, the two working frequencies of the dual-cavity dual-frequency solid laser device are stabilized simultaneously, the laser frequency stability is higher than 10<-10>, and the Pound-Drever-Hall frequency stabilizing system can be widely applied to fields of interferometry for absolute distances of synthesis waves, generation of THz waves and the like.

Description

Technical field [0001] The invention relates to a dual-cavity dual-frequency solid-state laser Pound-Drever-Hall frequency stabilization system. Background technique [0002] There are two main types of laser active frequency stabilization technology: One is to use the center frequency of the transition spectrum of atoms or molecules as the reference standard. Commonly used methods include frequency stabilization by Lamb recess, frequency stabilization by atomic spectrum Zeeman effect, and saturated absorption by atoms or molecules. Frequency stabilization; The second is based on the resonant cavity resonance frequency as a reference standard. Commonly used methods include phase offset frequency locking technology, derivative spectrum frequency stabilization technology and side frequency locking frequency stabilization technology. [0003] The frequency stabilization device of the Lamb notch frequency stabilization method is relatively simple, but the center frequency of the gain c...
