Abstract

Buried channel waveguides have been fabricated in Nd:GGG crystals by using the femtosecond laser inscription. The waveguides are confined between two filaments with propagation losses of 2.0 dB/cm. Stable continuous wave laser oscillation at ~1061 nm has been demonstrated at room temperature. Under 808 nm optical excitation, a pump threshold of 29 mW and a slope efficiency of 25% have been obtained.

摘要

通过飞秒激光写入技术在钕镓石榴石（Nd:GGG）晶体中制备了掩埋通道波导。这些波导被限制在两根细丝之间，传播损耗为2.0 dB/cm。在室温下已证明在~1061 nm处有稳定的连续波激光振荡。在808 nm光激发下，获得了29 mW的泵浦阈值和25%的斜率效率。
