Intracavity THz generation using a thin lithium niobate plate in a compact Kerr-lens mode-locked Yb:CALGO bulk oscillator
Mohsen Khalili, Jokūbas Pimpė, Yicheng Wang +5
We demonstrate intracavity terahertz (THz) generation via optical rectification in a 50-m-thick lithium niobate crystal placed inside a compact diode-pumped Kerr-lens mode-locked (…
Scaling of broadband Ho:CALGO regenerative amplifier to multi-mJ pulse energy
Anna Suzuki, Michael Müller, Sergei Tomilov +1
We report on energy scaling of a 2.08-μm wavelength regenerative amplifier (RA) system based on the broadband gain material Ho:CaAlGdO4 (CALGO) to multi-mJ pulse energy at kHz repe…
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…
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-Dynamic Range Broadband Terahertz Time-Domain Spectrometer Based on Organic Crystal MNA
Samira Mansourzadeh, Tim Vogel, Alan Omar +7
We present a high power and broadband THz-TDS setup utilizing the nonlinear organic crystal MNA both as emitter and detector. The THz source is based on optical rectification of ne…
