We demonstrate a 968-nm LD side-pumped Er:YAP laser with concave end-faces and a working frequency of 50∼1000 Hz. The maximum average powers of 26.75 and 13.18 W are obtained at 250 and 1000 Hz, corresponding to the slope efficiency of 16.2% and 9.0%, respectively. The M2 factors of 7.98 and 1.49 are determined under the multi-mode and single...... hiện toàn bộ
