Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 As shown, the structure schematic diagram of the high-power fast-response laser power supply of the present invention is given, which is composed of a main control board 1, a high-power power supply board 2, a base heat sink 3, and a cooling fan 4. The main control board 1 is fixed on a high-power On one side of the power board 2 , the heat sink 3 of the base is fixed on the other side of the power board 2 , and a plurality of cooling fans 4 are fixed on the heat sink 3 of the base. The heat dissipation fan 4 uses the grid groove on the heat sink 3 of the base as an air channel to increase the heat dissipation performance of the heat sink 3 of the base. Mounting holes are provided at the corresponding positions of the main control board 1 and the high-power power supply board 2. Use copper pillars or connectors of other material...

Abstract

The high-power fast-response laser power supply of the present invention includes a main control board and a high-power power supply board. The high-power power supply board is provided with a power filter circuit, a constant current control MOS tube, a high-power inductor and a laser power supply control MOS tube circuit, and is characterized in that : The laser power supply control MOS tube circuit is composed of multiple MOS tubes. The source of each MOS tube is connected to the power ground, and the drain is connected to the output terminal LD+ of the high-power inductor. LD+ is the power supply terminal of the laser element; the main control board A fast-discharging MOS transistor drive circuit is arranged on the top, and the source of the MOS transistor Q10 generates the LD_CTRL_MOS control signal. In the laser power supply of the present invention, under the control of LD_CTRL_MOS, the drain of the MOS tube in the laser power supply control MOS tube circuit is quickly cut off from the power supply, so that the laser element can be quickly turned on following the laser power supply signal, and the rise time can reach ns level. In turn, a us-level laser illumination signal can be formed.

Description

technical field [0001] The present invention relates to a high-power fast-response laser power supply, and more specifically, to a laser power supply capable of fast and controlled power-on of high-power lasers. Background technique [0002] High-power laser power supply quality requirements are high, and under some requirements, the laser needs to be powered on quickly to generate pulsed high-power laser beams. For example, in range-gated laser imaging products, a laser beam with a pulse width of several microseconds is required, and the laser beam requires the laser to emit light quickly. The rising edge of the laser power supply needs to reach the nanosecond level to meet the actual needs. At present, there is no corresponding high-power laser power supply with a nanosecond rise time in the market. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned technical problems, the present invention provides a high-power fast-respons...
