Abstract

End-pumped unidirectional ring lasers often suffer some degree of residual spatial hole burning, where a standing-wave region overlaps the pumped region. By non-concentric pumping this overlap can be reduced, thus increasing the output power level at which single frequency operation can be maintained. Experimental results show a factor of 2 to 3 improvement in single-frequency performance for only a small drop in output power.
