330 mJ single-frequency Ho:YLF slab amplifier

Author: Strauss, Hencharl J ; Preussler, D ; Esser, MJD ; Koen, W ; Jacobs, Cobus ; Collett, OJP ; Bollig, C Date: Apr 2013 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 laser and seeded with ... Read more
Controllable beam shaping of coherent and incoherent beams by a laser amplifier

Author: Litvin, Ihar ; King, Gary R Date: Aug 2018 We 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
Digital generation of shape-invariant Bessel-like beams

Author: Litvin, Igor A ; Collet, Oliver JP Date: Mar 2015 We 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
Ho:YLF & Ho:LuLF slab amplifier system delivering 200 mJ, 2 µm single-frequency pulses

Author: Strauss, Hencharl J ; Koen, W ; Bollig, C ; Esser, MJD ; Jacobs, Cobus ; Collett, OJP ; Preussler, DR Date: Jul 2011 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 seeded with a 69 mJ ... Read more
Optically pumped tunable HBr laser in the mid-infrared region

Author: Koen, W ; Jacobs, Cobus ; Bollig, C ; Strauss, Hencharl J ; Esser, MJD ; Botha, LR Date: Jun 2014 An 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
