摘要

我们介绍了掺镱磷酸盐玻璃埋入通道波导中的连续波激光作用。25 毫米长的波导是用标准离子交换法制造的。当使用波长为 976 nm 的激光二极管进行泵浦时，波导激光的发射波长为 982.4 nm，产生了 0.66 % 的超低量子缺陷。耦合和泵浦功率变化对激光发射波长的影响得到了证实。此外，还展示了使用单层石墨烯作为可饱和吸收体（SA）的脉冲结果，并获得了重复频率为 1 MHz、脉冲宽度为 700 ns 的脉冲序列。

A low quantum defect and power scalable Yb-doped glass waveguide laser

We present a continuous wave laser action in ytterbium (Yb)-doped phosphate glass buried channel waveguides. The 25 mm long waveguides were fabricated by the standard ion exchange method. When pumped with a 976 nm laser diode, the waveguide laser emits at 982.4 nm, yielding an ultralow quantum defect of 0.66 %. The impact of coupling and pump power variation on the laser emission wavelengths is demonstrated. Furthermore, the results of pulsing using a monolayer graphene as a saturable absorber (SA) are presented and a pulse train with a repetition rate of 1 MHz and a pulse width of 700 ns was obtained.

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
