| Abstract: | Laser with higher frequency, smaller dimension and wider band is required in underwater 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 conditions 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. |
