Laser Frequency Stabilization Control Card ZYNQ 7035
A dedicated control device for precision optical measurement and quantum technology research scenarios. Designed based on Modulation Transfer Spectroscopy (MTS), it realizes sub-kilohertz ultra-high stability locking of 532nm band laser frequency through a dual-channel feedback control mechanism. The system adopts external modulation technology to separate optical path tuning from light source output, and completes high-precision demodulation of detection optical sideband signals combined with four-wave mixing effect, overcoming industry bottlenecks of traditional saturated absorption spectroscopy including high power demand and significant linewidth broadening. It can fully meet high-end scientific research and engineering scenarios with extreme requirements for laser frequency stability such as cold atom experiments and gravitational wave detection.
