| Abstract: | This paper presents a method for laser linear modulation frequency.Due to the linear electro-optic effect of electro-optic crystal,a Linear Frequency Modulation(LFM)laser signal is realized by controlling the external electric field.By this method,a high frequency modulation rate and large modulation range can be realized to meet the requirements of the laser radar and range finder.The external circuit is simple and easy to control. |
