Abstract :
The paper reports an alternative and very simple strategy for directly generating a high quality LG01mode in a laser, which is especially well-suited for hybrid (fibre-laser-pumped) bulk solid-state laser architectures and hence offers the prospect of very high average output power in continuous-wave (cw) and pulsed modes of operation. Using this approach, the work has operated an Er:YAG laser, in-band pumped by an Er,Yb fibre laser, with a high quality radially-polarized LG01 mode output in cw and Q-switched mode of operation.
