AI Technical Summary
Technical Problem
In existing wind measurement radar systems, EDFA and AOM are large in size, consume a lot of power, and are expensive, which limits the miniaturization of the system and its application scope.
Method used
A semiconductor amplifier (SOA) is used to replace the EDFA and AOM. High-energy pulsed laser output is achieved through an extremely short pulse driving method, and it is turned off during non-working periods to reduce energy consumption. The semiconductor amplifier and pulse driving power supply are integrated to form an optical switch function.
Benefits of technology
It significantly reduces the size of the laser, lowers energy consumption, and improves the reliability and performance of the system, making it suitable for miniaturized and low-cost wind radar applications.
