Author:Strauss, Hencharl J; Preussler, D; Esser, MJD; Koen, W; Jacobs, Cobus; Collett, OJP; Bollig, CDate:Apr 2013We 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 laser and seeded with ...Read more
Author:Litvin, Ihar; King, Gary RDate:Aug 2018We propose the technique for a controllable manipulation of the transverse intensity distribution of an output beam by the temporal adjustment of a transverse gain profile in a laser amplifier. It was created by an independent manipulation ...Read more
Author:Litvin, Igor A; Collet, Oliver JPDate:Mar 2015We propose a new technique for laser beam shaping namely the reshaping of the laser beam into a desirable beam profile by the use of a laser amplifier with a pump beam that has a modified intensity profile. We developed the analytical formula ...Read more
Author:Strauss, Hencharl J; Koen, W; Bollig, C; Esser, MJD; Jacobs, Cobus; Collett, OJP; Preussler, DRDate:Jul 2011A 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 seeded with a 69 mJ ...Read more
Author:Koen, W; Jacobs, Cobus; Bollig, C; Strauss, Hencharl J; Esser, MJD; Botha, LRDate:Jun 2014An optically pumped tunable HBr laser has been demonstrated for the first time. The pump source was a single-frequency Ho:YLF laser and amplifier system, which was locked to the 2064 nm absorption line of HBr. Laser oscillation was demonstrated ...Read more
