Paper Abstract

This paper introduces method of electrical noise evaluating of high-power fiber coupled diode laser. After photoelectricity conversion of output laser, We measure its electrical noise by analyse and test system. At the same time, we find out primary noise source through analysing 1/f noise, G-R noise and burst noise in the device systematically. Moreover we raise feasible advice on how to improve arts level and reliability of system after analysing relationship between noise and correlative arts. Experimental result shows that this method is effective and practicable .
