Single-mode laser action has been demonstrated in a gain-guided, index-antiguided (GG IAG) Nd3+ doped phosphate glass fiber through the use of a diode side-pumping scheme. This pump technique can allow for length scaling of diode-pumped GG IAG fibers and therefore true power scaling of the GG IAG concept. Near-Gaussian beam quality was demonstrated with beam M2 of 1.4.
