摘要
We explore and demonstrate the feasibility of an optical-frequency-to-radio-frequency division method that is based on visible or near-infrared laser oscillators only. Comparing harmonic and sum frequencies, we generate the arithmetic average of two visible frequencies. Cascading n stages provides difference-frequency division by 2n. For a demonstration we have phase locked the second harmonic and the sum frequency of two independent diode lasers. © 1990 Optical Society of America.
