We grew oriented single crystals of BaYLuF8 and Nd:BaY 2F8 doped with Nd3+. An experimental investigation and comparison of the spectroscopic properties of the two crystals are presented to guide their use as lasing elements in solid-state lasers. The absorption and stimulated emission cross section of the Nd3+ 4F3/2 decay to the 4I9/2, 4I11/2 and 4I13/2 states, for light linearly polarized along the three principal axes, were obtained at room temperature. Nd:BaYLuF8 shows absorption and stimulated emission cross sections that are very similar to those of Nd:BaY2F 8, making it a good candidate for lasers. Because Nd:BaYLuF 8 is easier to grow than Nd:BaY2F8, it is a viable alternative as a laser medium. © 2011 Optical Society of America. Source

AC Materials proposes development of a 4 micron Ho:BaY2F8 laser pumped by a Cr:LISAF laser in response to Air Force needs for an efficient pulsed source in the 3-5 micron region. Under the Phase I program lasing at 3.9 micron was demonstrated, with over 30mJ power per pulse. The Phase II effort will be optimization of this Ho laser. Crystal growth of Cr:LiSAF and Ho:BYF will be advanced to enable production of optimized laser crystals. With the optimization of the crystals and cavity geometry, theresulting laser system is expected to provide 200 mJ at 3.9 micron, with a repetition rate of 10 Hz, and acceptable beam quality.
