附注	we report on a master-oscillator fiber power amplifier (mopa) system with a core diameter of only 20 mu m and 6-m-long yb3+-doped large mode area (lma) double-clad fiber. actively q-switched nd:yvo4 laser is used as a seed source of light pluses. the system works at the repetition rate from 40 to 100 khz. up to 77 w of amplified radiation with the pulse duration of 17.8 ns at the wavelength of 1064 nm and repetition rate of 40 khz are generated, corresponding to pulse energy of 1.9 mj and the slope efficiency of 73.5%. in reported literatures, the 77 w is the highest average power with a 20-mu m-core lma fiber to our knowledge. the stimulate brillouin scattering (sbs) is observed and investigated.
