Abstract : Based on the summarizing of the basic principle , main characterisTIcs of fiber laser and several methodsfor its classificaTIon , this paper introduces the working principle of cladding pumped fiber laser as well as its recent de 2velopment . Then the generaTIng mechanism of mulTI2wavelength fiber laser is presented through analyzing several clas 2sical experimental instruments. The paper discusses three techniques for fiber laser to generate mode 2locking pulse , in2cluding active mode2locking technique using magnitude or phase modulator , passive mode 2locking technique using non2linear effect and hybrid locking technique. A comparison between the performances of these three experimental instru 2ments is made and their recent developments are also included.Key words : fiber laser ; fiber grating ; clad pumping technology ; active mode2locking ; passive mode2locking ; re2generative mode2locking ; OTDM; DWDM
