It was found experimentally that stimulated emission from a fiber laser made of neodymium-doped phosphate glass could operate in quasi-cw and structured spike regimes, depending on the content of cerium oxide in the glass. The total half-width of the emission spectrum of such a fiber laser did not exceed 1.0--1.2 nm when the pump energy exceeded the threshold by a factor of 4.5. The time dependence of the intensity of stimulated radiation was influenced mainly by the presence or otherwise of short-lived color centers absorbing at the laser emission wavelength lambda = 1.06 ..mu.., which were created in glass by the ultraviolet part of the pump radiation.
