Ho3+-doped CALGO crystals for high-power ultrafast 2.1-μm lasers
Anna Suzuki, Pavel Loiko, Weichao Yao +8
Ho3+-doped disordered CaAlGdO4 (CALGO) crystals have recently emerged as a promising gain material platform for next-generation high-power ultrafast 2.1-μm laser systems. This lase…
Laser-driven few-cycle Terahertz sources with high average power
Robin Löscher, Tim Vogel, Samira Mansourzadeh +5
Ultrafast laser-driven terahertz sources are gaining in popularity in an increasingly wide range of scientific and technological applications. However, many fields continue to be s…
Energy scaling of Kerr-lens modelocked Ho:YAG thin-disk oscillators to the microjoule level
Sergei Tomilov, Mykyta Redkin, Yicheng Wang +3
We demonstrate peak power and pulse energy scaling of Kerr-lens modelocking (KLM) Ho:YAG thin-disk lasers (TDLs) emitting at 2.1-μm wavelength. We compare different laser configura…
Ytterbium-laser-driven THz generation in thin lithium niobate at 1.9 kW average power in a passive enhancement cavity
Edoardo Suerra, Francesco Canella, Dario Giannotti +8
Single-cycle, high-power, high-repetition-rate THz pulse sources are becoming the cornerstone of several scientific and industrial applications. A promising and versatile method fo…
High-power single-cycle THz emission from large-area photoconductive emitters at 400 kHz
Mohsen Khalili, Yicheng Wang, Stephan Winnerl +1
We report high average power THz emission from a GaAs-based large-area photoconductive emitter, excited by a commercial Yb-laser amplifier without any compression schemes, doubled…
High peak-power 2.1-μm femtosecond Holmium amplifier at 100 kHz
Anna Suzuki, Boldizsar Kassai, Yicheng Wang +5
High-power ultrafast laser sources in the short-wave infrared region are of great interest for numerous applications, including secondary sources of radiation and processing of mat…
