Abstract :
1.5 W of 1st Stokes, 1167 nm, cw output power was produced using a Nd:YLF laser crystal associated to a BaWO4 Raman crystal. The laser built provided a M2 of 1.51 and 1.43, vertical and horizontal, respectively. This high beam quality and Watt level power laser was built in a long cavity, demonstrating the advantages of Nd:YLF, which will ultimately enable low amplitude noise Raman lasers and allowing long length cavity geometries, such as “V” shape, for better conversion efficiencies. A preliminary result for a cw 583 nm laser has delivered 0.61 W of output power.
