We report high efficiency continuous wave laser oscillations at 1063.6 nm from an ultrafast laser written Nd(3+):GdVO4 channel waveguide under the 808 nm optical excitation. A record 17 mm·s(-1) writing speed was used while the low propagation loss of the waveguide (~0.5 dB·cm(-1)) enabled laser performance with a threshold pump power as low as 52 mW and a near to quantum defect limited laser slope efficiency of 70%.
我们报道了在808 nm光激发下，超快激光写入的Nd(3+):GdVO4通道波导在1063.6 nm处实现了高效连续波激光振荡。使用了创纪录的17 mm·s(-1)写入速度，同时波导的低传播损耗（~0.5 dB·cm(-1)）使得激光性能得以实现，阈值泵浦功率低至52 mW，接近量子缺陷极限的激光斜率效率为70%。
