Powerful and compact sources are desirable for massive production of 3He gas. A new generation of fiber lasers is now available. The master oscillator power amplifier design relies on the use of a seed fiber laser which has adjusted linewidth of 1.8GHz to achieve optimum pumping of 3He and 4He atomic transitions. In particular, the small free spectral range of the seed oscillator allows many longitudinal modes to fill the linewidth, which leads to high transition pumping efficiency. High power fiber amplifier built with the latest generation of high power fiber components, amplify the seed laser up to 20W of output power.
