We demonstrated the efficient guided laser action in a diode-pumped YAG/Nd:YAG/YAG ceramic planar waveguide produced by tape casting and vacuum sintering technology for the first time to the best of our knowledge. In the regime of continuous wave operation, a maximum output power of 840 mW corresponding to the slope efficiency of 65% was achieved. During passively Q-switched operation, by replacing the dichroic mirror with graphene-oxide based output coupler, we obtained the stable pulse trains with the shortest pulse duration of 179 ns at a pulse repetition rate of 930 kHz which resulted in the single pulse energy of 221 nJ.
据我们所知,我们首次在通过流延成型和真空烧结技术制备的二极管泵浦YAG/Nd:YAG/YAG陶瓷平面波导中展示了高效的激光导波作用。在连续波运行模式下,实现了840 mW的最大输出功率,斜率效率为65%。在被动调Q运行期间,通过用基于氧化石墨烯的输出耦合器替换二向色镜,我们获得了稳定的脉冲序列,在930 kHz的脉冲重复频率下,最短脉冲持续时间为179 ns,单脉冲能量为221 nJ。
