Fiber lasers are a fast growing class of lasers due to their reliability, efficiency and flexibility. This has made fiber lasers a versatile tool for manufacturing, sensing and healthcare, not forgetting the contribution of Erbium-doped amplifiers to optical communications. Yet available wavelengths by direct emission are quite restricted to the visible and(More)
We present a new survey of HCN (1–0) emission, a tracer of dense molecular gas, focused on the littleexplored regime of normal star-forming galaxy disks. Combining HCN, CO, and infrared (IR) emission, we investigate the role of dense gas in star formation, finding systematic variations in both the apparent dense gas fraction (traced by the HCN-to-CO ratio)(More)
