Embodiment Construction
[0015] The invention is an underwater laser sounder without a sound transducer. figure 2 The principle block diagram of the underwater laser sounder is given, image 3 A schematic diagram of the structure of the underwater laser sonicator is given. In the following, only 5 lasers in the laser group are taken as an example and described in detail with reference to the accompanying drawings.
[0016] The underwater sound generator is composed of a 2-3 micron laser group 1, a laser power supply 2, a fiber coupler group 3, a conductive fiber group 4, a control box 5 and a bracket 6. Among them, the 2-3 micron laser group 1 is composed of five hosts of 2.94 micron solid-state pulsed lasers. The output wavelength of each laser is 2.94 microns, the pulse energy is 0.1-5J, the repetition frequency is 1-40Hz, and the pulse width is 0.3ms. Pu way. The laser power supply 2 has the power supply capability to guarantee the simultaneous operation of 5 lasers, and the trigger frequency c...
