    Of the various Neodymium-doped materials, Nd:YLF is particularly attractive for use in high-power diode endpumped solid-state lasers due to its weak thermal lens, especially on the σ-polarisation, and it’s long upper laser ...
  • Schellhorn, M; Ngcobo, SH; Bollig, C; Esser, MD; Preussler, DR; Nyangaza, K (Institute of Electrical and Electronic Engineering (IEEE), 2009-06)
    The aim is to develop a high-power Tm:YLF slab laser which can be utilized to pump a Ho slab laser. A 68 W Tm:YLF slab laser was recently presented in [1] pumped from one end by a single 6-bar stack delivering ~300 W of ...
  • Strauss, HJ; Koen, W; Bollig, C; Esser, MJD; Jacobs, Cobus; Collett, OJP; Preussler, DR (Optical Society of America, 2011-07)
    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 ...
  • Botha, LR; Bollig, C; Esser, MJD; Campbell, RN; Jacobs, Cobus; Preussler, DR (Optical Society of America, 2009-10)
    A Ho:YLF laser pumped HBr molecular laser was developed that produced up to 2.5mJ of energy in the 4 micron wavelength region. The Ho:YLF laser was fiber pumped using a commercial Tm:fibre laser. The Ho:YLF laser was ...
