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
Efficient Ho:YLF laser pumped by a Tm:fiber laser

Author: Koen, W ; Jacobs, Cobus ; Collett, O ; Esser, MJD Date: Oct 2013 A thulium fiber laser pumped Ho:YLF laser delivering 45.1 W in a near diffraction limited beam when pumped with 84.7 W is demonstrated. The optical-to-optical efficiency of 53 % compares favorably with similar Ho:YAG lasers. Read more
High average power Q-switched 1314 nm two-crystal Nd:YLF laser

Author: Botha, RC ; Koen, W ; Esser, MJD ; Bollig, C ; Combrinck, WL ; Von Bergmann, M ; Strauss, Hencharl J Date: Feb 2015 A 1314 nm two-crystal Nd:YLF laser was designed and operated in both CW and actively Q-switched modes. Maximum CW output of 26.5 W resulted from 125 W of combined incident pump power. Active Q-switching was obtained by inserting a Brewster-cut ... 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
