摘要
就水下探测设备要求激光器输出频率高、体积小、波段宽,提出通过侧面泵浦激光技术和电光调Q技术获得高重频1 064nm波段激光。利用腔外波长变换技术,实现532nm激光输出。在电源输入电流100A,调Q驱动频率1kHz的条件下,获得36 mJ的1 064nm激光输出和20mJ的532nm激光输出。试验结果表明:通过半导体泵浦技术和频率变换技术,可实现高重频窄脉宽双波段激光输出。
Laser with higher frequency, smaller dimension and wider band is required in underwa- ter detection. We proposed the 1 064 nm miniaturization laser with high repetition frequency could be obtained by side-pumped laser technology and EO Q-switched technology, and 532 nm laser output could be achieved by extra-cavity-doubled frequency conversion. 1 064 nm laser with output energy of 36 mJ and 532 nm laser with output energy of 20 mJ were obtained under condi- tions of 100 A power input current and 1 kHz Q-drive frequency. Results indicate that dual-band miniaturization laser with output of high pulse repetition frequency and narrow pulse width can be realized by diode-pumped laser technology and frequency conversion technology.
