Paper Abstract

We report on a diode pumped Tm: YLF laser generating 1.9 micrometers output. Recently, research is being pursued to produce laser wavelength around 2 micrometers by separating the Ho and Tm ions in different laser hosts. Compared to co-doped laser hosts; a higher efficiency performance can be achieved by directly pumping the Holmium with a 1.9 micrometers Tm laser due to the elimination of energy sharing between Tm and Ho as well as deleterious upconversion effects in co-doped systems. A 300-mJ Tm:YLF laser at room temperature has been demonstrated. The laser design and laser performance is described. To our knowledge, this is the highest energy ever reported for this laser material.
