    We report on a double-pass Ho:YLF slab amplifier which delivered 350 ns long single-frequency pulses of up to 330 mJ at 2064 nm, with a maximum M(sup2) of 1.5 at 50 Hz. It was end pumped with a diode-pumped Tm:YLF slab ...

    A single-frequency single-pass amplifier based on Ho:YLF and Ho:LuLF in a scalable slab architecture delivering up to 210 mJ at 2064 nm is demonstrated. The amplifier was end-pumped by a 1890 nm Tm:YLF slab laser and was ...

    A novel multi-pass Tm: YLF laser was demonstrated with an improvement in efficiency, footprint and cost over a two diode stack pumped, single pass system. 100 W of output power from 261 W of incident diode pump power with ...
