  • Fiber amplifiers at 1.5 μm for laser sources in next-generation gravitational wave detectors 
    de Varona Ortega, Omar (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)
    After the first direct detection of gravitational waves (GWs) in 2015, the feasibility of GW-astronomy as a complementary method to carry out astrophysical and cosmological observations on a regular basis has been reaffirmed. ...
  • Fiber modulators and fiber amplifiers for LISA 
    Tröbs, Michael; Barke, S.; Möbius, J.; Engelbrecht, M.; Theeg, T.; Kracht, D.; Sheard, Benjamin; Heinzel, Gerhard; Danzmann, Karsten (Bristol : IOP Publishing Ltd., 2010)
    We present the sideband phase characteristics of a fiber-coupled integrated electro-optical modulator (EOM) at a modulation frequency of 2 GHz for Fourier frequencies from 0.1 mHz to 1 Hz. The upper phase noise limit was ...
  • High power, single-frequency, monolithic fiber amplifier for the next generation of gravitational wave detectors 
    Wellmann, Felix; Steinke, Michael; Meylahn, Fabian; Bode, Nina; Willke, Benno; Overmeyer, Ludger; Neumann, Jörg; Kracht, Dietmar (Washington, DC : OSA - The Optical Society, 2019)
    Low noise, high power single-frequency lasers and amplifiers are key components of interferometric gravitational wave detectors. One way to increase the detector sensitivity is to increase the power injected into the ...
  • High repetition rate, J-level, CPA-free ultrashort pulse multipass amplifier based on Ho:YLF 
    Hinkelmann, Moritz; Wandt, Dieter; Morgner, Uwe; Neumann, Jörg; Kracht, Dietmar (Washington, DC : Optical Society of America, 2018)
    We report on CPA-free multipass amplification of ps-pulses in Holmium-doped yttrium lithium fluoride (Ho:YLF) crystals up to µJ pulse-energy-covering repetition rates from 10 kHz up to 500 kHz. The seed pulses at a wavelength ...
  • Innovative laser sources operating around 2 μm 
    Kracht, D.; Sayinc, H.; Yilmaz, S.; Wysmolek, M.; Hausmann, K.; Ottenhues, C.; Wandt, D.; Wienke, A.; Neumann, J. (Amsterdam : Elsevier B.V., 2016)
    We report on a variety of continuous wave and pulsed laser sources based on Thulium- and Holmium-doped materials, emitting in the spectral range around 2 μm. This includes continuous wave Thulium-doped fiber lasers which ...
  • Low noise 400 W coherently combined single frequency laser beam for next generation gravitational wave detectors 
    Wellmann, Felix; Bode, Nina; Wessels, Peter; Overmeyer, Ludger; Neumann, Jörg; Willke, Benno; Kracht, Dietmar (Washington, DC : Optica, 2021)
    Design studies for the next generation of interferometric gravitational wave detectors propose the use of low-noise single-frequency high power laser sources at 1064 nm. Fiber amplifiers are a promising design option because ...
  • Rapidly tunable femtosecond near-UV pulses from a non-collinear optical parametric oscillator 
    Geesmann, Fridolin Jakob; Mevert, Robin; Zuber, David; Morgner, Uwe (Washington, DC : Optica, 2023)
    Broadband tunable femtosecond laser pulses are of great interest in numerous fields, such as spectroscopy or imaging. Here, we report on the generation of rapidly tunable radiation in the near UV by using intracavity ...
  • Ultrashort pulse CPA-free Ho:YLF linear amplifier 
    Hinkelmann, Moritz; Wandt, Dieter; Morgner, Uwe; Neumann, Jörg; Kracht, Dietmar (Bellingham, WA : S P I E - International Society for Optical Engineering, 2018)
    We present CPA-free linear amplification of 6:3 ps pulses in Ho:YLF crystals up to 100 μJ pulse energy at 10 kHz repetition rate. The seed pulses at a wavelength of 2:05 μm are provided by a Ho-based all-fiber system ...
