Compact fibre-laser-pumped Ho:YLF oscillator-amplifier system

Author: Bollig, C ; Strauss, Hencharl J ; Esser, MJD ; Koen, W ; Schellhorn, M ; Preussler, D ; Nyangaza, K ; Jacobs, Cobus ; Bernhardi, EH ; Botha, LR Date: Jun 2009 Ho:YLF is an attractive laser material for 2 µm high energy sources since it has a much longer upper laser level lifetime (~14 ms) and higher emission cross section than Ho:YAG. In addition, the very weak thermal lens on the polarisation helps ... Read more
Compact fibre-laser-pumped Ho:YLF oscillator–amplifier system

Author: Koen, W ; Bollig, C ; Strauss, Hencharl J ; Schellhorn, M ; Jacobs, Cobus ; Esser, MJD Date: Apr 2010 The authors developed a compact Ho:YLF oscillator–amplifier system in a novel setup to utilise the unpolarised pump power from a fibre laser efficiently, and produced 21.3 mJ at 1 kHz, with an M 2 better than 1.1. The amplified energies agreed ... Read more
High-power diode-pumped Tm:YLF slab laser

Author: Schellhorn, M ; Ngcobo, S ; Bollig, C ; Esser, MD ; Preussler, DR ; Nyangaza, K Date: Jun 2009 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 pump power. In this ... Read more
