Problems solved by technology

The existing modules have the following disadvantages: 1. The energy conversion chip is packaged in TO, generally TO46 or TO39. Due to the small area of ​​the TO base, the heat dissipation effect is poor, and the increase in temperature leads to a decrease in the efficiency of the laser energy conversion chip and poor output performance. Low reliability, not conducive to long-term stable operation
2. The flange is made by machining or die-casting process. The precision of the inner hole of the optical fiber connector is up to 0.05mm. When inserting different laser fibers, the optical fiber and the flange cannot be tightly matched, and looseness can be felt, resulting in poor consistency of product output performance
3. TO packaging is adopted, and the sealing cap adopts parallel sealing welding or energy storage welding. The equipment used is expensive, the process is complicated, and the cost is high, which is not conducive to mass production

Description

technical field [0001] The invention belongs to the technical field of improving laser functional systems, in particular to an energy conversion module for a laser energy supply system. Background technique [0002] The laser energy conversion module is connected to the semiconductor laser through an optical fiber. The optical fiber transmits the laser light to the laser energy conversion module, converts the laser energy into electrical energy, and provides the required electrical energy for the terminal equipment, which can transmit the energy to hundreds of meters or even thousands of meters. At the same time, because the laser is transmitted in the optical fiber, it is completely insensitive to high temperature, low temperature, radiation and electromagnetic interference. Sensors and acquisition circuit power supply, etc., can be used in nuclear magnetic resonance equipment in the medical field, in wind power generator health detection systems, and in aircraft fuel tank ...
