Abstract
We report on an glass laser pumped by a laser emitting at 889 nm. glass is a promising material for direct mid-infrared lasers around 4 μm. To evaluate the performances of this new material, we compared it to an crystalline laser pumped by the same source. At 650 mJ pump energy, 7.2 mJ (46 mJ) was obtained with (), respectively. This is, to the best of our knowledge, the first reported laser activity in this type of glass.
