microputer control technology to measure the way of the bination of the laser power solution, is very mon and effective way, and optical fiber laser is also widely used in low power marking, sculpture, etc, and at the same time to a higher power of metal and ceramic cutting, welding aspect development.This issue analyzes the pulse optical fiber laser fundamental principle and detailed measure and display pointed out the laser power train of thought and required consider problems, through the missioning and analysis the design of the system structure, finally plete the whole of optical fiber laser power detection and display.The thesis work is mainly reflected in the following areas:(1) Collected laster signal fitering, amplification circuit.(2) Peak hold circuit to AC signals DC, peak to peak signal.(3) STC89C52 microcontroller part of the design and software programming. The system circuit design reasonable, stable, the performance good, detection speed, simple calculation, easy to do realtime control, and in the measurement precision can reach industry practical requirement.Keywords: Fiber laser。盡管目前多數(shù)類型的器件仍處于實(shí)驗(yàn)室研制階段，但已經(jīng)在實(shí)驗(yàn)室中充分顯示其優(yōu)越性。不久以后，光纖激光器被用于光學(xué)信息處理方面的工作，但由于當(dāng)時(shí)條件的限制，此后光纖激光器的發(fā)展
