With the development of laser technology, the peak power of laser pulse reaches 10¹² W, and the pulse duration reaches femtosecond or even attosecond level. The emergence of ultra-short and ultra-intense laser pulse technology has brought great challenges and development opportunities to the military field, especially the mid-infrared band laser pulse has a huge application prospect in laser warning technology, laser detection, laser active guidance, etc. However, due to the insensitivity of the existing detection technology to femtosecond and attosecond laser pulses, a new femtosecond laser pulse detection technology is urgently needed, this paper proposes a super-resolution coherent detection method for mid-infrared band laser pulses and conducts an in-depth analysis of its detection mechanism, which has the advantages of high detection accuracy and high sensitivity, and can be applied to the laser guidance technology with femtosecond or even attosecond pulses as the active light source in the future, which lays a technical foundation for the application of femtosecond and attosecond laser pulses in the military field.
