Development of a mid-IR Laser
We developed a fiber laser at 1925 nm using a thulium-doped fiber as the gain medium. This laser has potential application in trace gas sensing responsible for climate change. For the first time aqueous solution of nanomaterials was used to produce tunable pulsed lasers. The designed laser required lower pump power compared to that previously reported. Also, the developed laser is compact and cost-effective to manufacture. We accomplished several important milestones, shaping future research endeavours in developing mid-IR lasers.
