We present a shot-noise limited SRS implementation providing a >200 mW per excitation wavelength that is optimized for addressing two molecular vibrations simultaneously. As the key to producing a 3 ps laser of different colors out of a single fs-las

High-repetition rate, mid-infrared, picosecond pulse generation with µJ-energies based on OPG/OPA schemes in 2-µm-pumped ZnGeP

We report on two different concepts to generate µJ-level mid-infrared laser pulses with sub-10 ps pulse duration via nonlinear parametric generation at high pulse repetition rates. Both schemes rely on the recent development of compact and efficient

Publikováno v: Nonlinear Frequency Generation and Conversion: Materials and Devices XIX.

We present a MgO:PPLN- and AgGaSe2-based, picosecond OPG/OPA scheme, enabling the generation of mid-to-long-infrared continuously tunable, microjoule energy pulses with a narrow spectral bandwidth of sub-8 cm-1 over the full tuning range. The approac

We revisit laser intensity noise in the context of stimulated Raman scattering (SRS), which has recently proved to be a key technique to provide label free images of chemical bonds in biological and medical samples. Contrary to most microscopy techni

Publikováno v: 2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC).

The mid-to-long-infrared spectral range (3–15 μm) is of high interest for a multitude of material processing and spectroscopic applications due to wavelength-specific absorption features of many polymers and organic molecules in this spectral regi
