High power single frequency operation and efficient intracavity frequency doubling of a Nd:YAG ring laser pumped by a diode bar
High power single frequency operation and efficient intracavity frequency doubling of a Nd:YAG ring laser pumped by a diode bar
Scaling single-frequency and visible intracavity-frequency-doubled diode-pumped solid-state lasers to multi-watt power levels is an area in which has attracted a great deal of interest due to the many potential applications of such sources. Ideally this should be achieved with the high overall efficiencies that have been such a notable feature of many lower power diode-pumped solid-state lasers. However, power scaling of the diode array pump lasers has led to output beams which are characteristically very asymmetric with M2 beam quality factors for orthogonal planes which typically differ by a factor of more than a 1000. This has rendered these devices very difficult to focus to small spot sizes and to use efficiently in end-pumped configurations.

Abstract
Scaling single-frequency and visible intracavity-frequency-doubled diode-pumped solid-state lasers to multi-watt power levels is an area in which has attracted a great deal of interest due to the many potential applications of such sources. Ideally this should be achieved with the high overall efficiencies that have been such a notable feature of many lower power diode-pumped solid-state lasers. However, power scaling of the diode array pump lasers has led to output beams which are characteristically very asymmetric with M2 beam quality factors for orthogonal planes which typically differ by a factor of more than a 1000. This has rendered these devices very difficult to focus to small spot sizes and to use efficiently in end-pumped configurations.
