AI Technical Summary
Existing thermoelectric laser detectors suffer from short lifespans, high failure rates, and inability to withstand high average power optical measurements due to the susceptibility of aluminum alloy substrates to damage, easy contamination of optical absorption coatings, material mismatch leading to thermopile detachment, and insufficient high-temperature resistance.
Using black silicon carbide ceramic as the heat-conducting plate and light absorber to replace the traditional three-layer structure, black silicon carbide ceramic has high thermal conductivity, low coefficient of thermal expansion, high temperature resistance and high optical damage threshold. It can be directly combined with thermopile to avoid material mismatch and thermal expansion problems, and the optical absorption surface can be cleaned by grinding.
It improves the optical damage threshold of laser detectors, reduces the failure rate, extends service life, simplifies the structure, reduces maintenance costs, and is suitable for ultra-high power optical measurements.
