We demonstrated a watt-level continuous-wave intracavity diamond Raman laser operating at 1634 nm in the eye-safe spectral region. By employing a dual Nd:YVO₄ crystal pumping configuration in combination with a Z‑shaped cavity design, the thermal lensing effect in the laser crystal was significantly suppressed. Consequently, the maximum injected pump power was increased from 40 W in a single-crystal scheme to 130 W, yielding 18.4 W of fundamental laser at 1342 nm.

1 Introduction Microbial Fuel Cells (MFCs), as an emerging eco-friendly energy technology, have garnered extensive attention in recent years [1]. MFCs boast numerous advantages such as high efficiency, renewability, low cost, and environmental friendliness [2], positioning them as a crucial component of future sustainable energy systems. Therefore, MFCs hold promising applications in various fields including wastewater treatment, biosensors, plant monitoring, and remote energy supply [3].
