Abstract

Using a high-Q diamond microresonator (Q>300,000) interfaced with high-power-handling directly-written doped-glass waveguides, we demonstrate a Raman laser in an integrated platform pumped in the near-visible. Both TM-to-TE and TE-to-TE lasing is observed, with a Raman lasing threshold as low as 20 mW and Stokes power of over 1 mW at 120 mW pump power. Stokes emission is tuned over a 150 nm (60 THz) bandwidth of approximately 875 nm wavelength, corresponding to 17.5% of the center frequency.

摘要

我们使用一个与高功率处理直接写入的掺杂玻璃波导相连接的高品质因子金刚石微谐振器（Q>300,000），在一个集成平台上展示了一种在近可见光波段泵浦的拉曼激光器。观察到了从横磁（TM）到横电（TE）以及从TE到TE的激光发射，拉曼激光阈值低至20毫瓦，在120毫瓦泵浦功率下斯托克斯功率超过1毫瓦。斯托克斯发射在中心波长约875纳米的150纳米（60太赫兹）带宽内可调谐，对应于中心频率的17.5%。
