Compact Diode-pumped Ultra-broad Wavelength Tunable Fiber Laser Source at 3 Micro

Compact diode-pumped mid-infrared laser sources with broad wavelength tunability have attracted considerable attention for many years because of their practical and potential applications in laser surgery, spectroscopy, remote sensing, optical pump sources for longer wavelength infrared oscillators, and infrared countermeasures. Based on the current research result of a new codoped glass material at the University of Arizona, TIPD proposes a STTR program to develop diode-pumped mid-infrared fiber laser at 3 mm with wavelength tuning range > 500 nm.  In this phase I program, we will focus on the fiber design and the demonstration of diode-pumped fiber laser at 3 mm with the new fiber.  A compact 10-W wavelength tunable fiber laser at 3 mm will be developed in Phase II.
