Diode-Pumped Tunable 3 Micron Laser Sources
Abstract
The purpose of this work was to evaluate two laser host materials doped with Tm and Dy as potential 3 um, diode pumped lasers. BaY2Fs single crystals were grown and spectroscopy identified efficient Tm to Dy energy transfer. The Dy stimulated emission cross section was measured to be comparable to other IR lasers. A new crystalline structure, NaYF4 was also studied. In this crystal it was found, in addition to efficient pumping, a longer fluorescent lifetime for the 3 um Dy laser transition. Both materials are promising candidates for a tunable 3 um laser source. Potential benefits: A compact, power scalable frequency agile solid state laser operating near the 3 um spectral hand is a desired technology for numerous BMDO and DOD programs including various active sensor and countermeasure applications. Commercial applications would he in the area of laser surgery, dentistry and dermatology. Further potential applications would be in instrumentation for scientific and spectroscopic studies, especially the 0-H bond.
