Tc. Ralph et al., HIGH-POWER QUENCHING RESULTING FROM PUMP EXCITED-STATE ABSORPTION IN AN ERBIUM-DOPED FIBER LASER, Optics letters, 18(14), 1993, pp. 1162-1164
We present an interesting theoretical prediction from semiclassical la
ser theory, namely, the quenching of laser action at high pump powers
that results from the presence of excited-state absorption of pump pho
tons. Experimental results are shown from an erbium-doped fiber laser
that are consistent with our prediction.
