為了提高現(xiàn)代武器系統(tǒng)在惡劣電磁環(huán)境中的通信和信息交換能力，充分利用激光的天然保密性，減少對無線電頻率資源的占用，對無線激光通信系統(tǒng)中的光發(fā)射模塊進(jìn)行了設(shè)計。在信標(biāo)光發(fā)射模塊的設(shè)計中采用驅(qū)動電路與溫度控制電路分離的設(shè)計方案;在信號光發(fā)射模塊中采用摻銀鉺光纖放大器(EDFA)作為功率放大器的設(shè)計方案，并采用DS90LV001芯片完成PECL信號與LVDS信號轉(zhuǎn)換。試驗結(jié)果表明，信標(biāo)光的最高輸出功率為1.53 W，最高頻率大于10 kHz;信號光的輸出功率大于19.8 dBm，誤碼率低于10-7，消光比為10.2 dBm，完全滿足設(shè)計需求。

　　Abstract:

　　In order to improve the communication and information exchange capability of modern weapons systems in the harsh electromagnetic environment，an optical transmitter of wireless laser communication system is designed，which fully uses the laser?蒺s natural confidentiality，and reduces the occupancy of radio frequency resources. A program of dissociating driving circuits and temperature control circuits is used in the beacon transmitter module design. In the signal optical transmitter module，EDFA is used as power amplifier，and the conversion between PECL signal and LVDS signal is completed by DS90LV001 chip. Experimental results show that the design can meet the performance requirements. The highest beacon output power is 1.53W，maximum frequency is greater than 10kHz， signal light output power is greater than 19.8dBm， bit error rate is less than 10-7，and the extinction ratio is 10.2dBm.
