Latest Patents

Elizabeth D Filer holds a patent for her invention titled "Ho:LuLF and Ho:Tm:LuLF laser materials." This patent describes a laser host material, LuLF (LuLiF.sub.4), which is doped with holmium (Ho) and thulium (Tm). The new laser material is capable of producing laser light in the vicinity of 2 μm. The LuLF host material offers advantages in efficiency over conventional Ho lasers, as it allows for decreased threshold and upconversion compared to hosts like YAG and YLF. Additionally, the incorporation of Tm enables pumping by commonly available GaAlAs laser diodes. For applications involving flashlamp pumping, erbium (Er) can be added as an additional dopant. Furthermore, to reduce upconversion, Tm can be eliminated, allowing for direct pumping of Ho.
