AbstractIn this thesis, high pulse energy single frequency fiber laser at 2 micron wavelength is designed and constructed with thulium-doped silicate fiber amplifiers. Starting from designing the polarization-maintaining (PM) thulium-doped silicate fiber amplifiers with master oscillator power amplifier (MOPA) configuration, three different Tm-doped fibers with core size 30 μm, 40μm, and 60 μm are assembled. Testing the fiber amplifiers with continues wave (CW) lasers at 1950 nm and 1977 nm, the final output power can reach as high as 30 W. Using five stages of amplifiers in the laser system, an all-fiber nanosecond single frequency laser at 1977 nm with 1.65 millijoules pulse energy output was firstly assembled.
