Optical frequency combs from ultrafast solid-state and semiconductor lasers
(2020)Proceedings of SPIE ~ Metamaterials, Metadevices, and Metasystems 2020A fully stabilized optical frequency comb provides equally spaced frequencies for a precise ruler in optical frequency metrology. This talk will review recent progress in single and dual comb generation from diode pumped solid-state and vertical emitting semiconductor lasers. A modelocked integrated external-cavity surface-emitting laser (MIXSEL) integrates both the gain and the saturable absorber layer within the same semiconductor wafer ...Other Conference Item -

Precise mid-infrared characterization of InGaSb/GaSb SESAMs
(2021)2021 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC)There is a strong interest in mid-infrared (mid-IR) Semiconductor Saturable Absorber Mirrors (SESAMs) [1]. We have established an accurate nonlinear reflectivity and time-resolved SESAM characterization which covers a wavelength range from 1.9 μm to 3 μm transferring our near-IR knowhow [2] , [3] to the mid-IR ( Fig. 1a , 1b ). The nonlinear reflectivity of a SESAM is characterized by the saturation fluence, modulation depth, non-saturable ...Other Conference Item -
Mid-infrared type-I InGaSb/GaSb quantum well SESAM
(2021)2021 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC)A Semiconductor Saturable Absorber Mirror (SESAM) is a key optical component used extensively for passively modelocking of diode-pumped solid-state and semiconductor disk lasers. Modulation depth (ΔR), saturation fluence (F sat ), non-saturable losses (ΔR ns ) and recovery times are the key parameters of a SESAM, which depend on semiconductor layer design and growth parameters. It has been shown that the recovery dynamics of InGaSb-based ...Other Conference Item -
High-Peak Power Single-Cavity Dual-Comb Solid-State Laser with 100-fs Pulse Duration
(2021)2021 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC)Dual-comb laser sources offer significant performance advantages compared to traditional laser sources in various optical sensing applications, such as high-resolution spectroscopy, rapid pump-probe measurements and ranging [1] . Dual-comb generation from a single laser cavity is particularly relevant for advancing practical dualcomb applications due to reduced complexity and cost. By using a birefringent polarization multiplexing of the ...Other Conference Item -
40 W SESAM-modelocked Ho:YAG thin-disk laser at 2090 nm
(2021)2021 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC)High power ultrafast lasers in the short-wave mid-IR wavelength region (2-3 µm) are of great interest for a large number of applications in science and technology. Finding paths to increase the average power of ultrafast laser systems directly emitting in this wavelength region has seen particularly strong interest, due to the potential of these sources as direct drivers for the generation of XUV, mid-IR and THz. Among different power-scalable ...Other Conference Item -
