Three-photon excitation has recently been demonstrated as an effective method to perform intravital microscopy in deep, previously inaccessible regions of the mouse brain. The applicability of 3-photon excitation for deep imaging of other, more heter

We report an optical parametric amplifier (OPA), providing a maximum pulse energy of ∼200 µJ at 700-950 nm and a pulse duration of ∼1 ps. The OPA is driven by a ∼1 ps pulse with ∼2.5 mJ energy at 1 kHz, provided by a commercial thin-disk bas

Orientation-patterned GaAs0.85P0.15 is grown by hydride vapor phase epitaxy on a GaAs template and second-harmonic generation is demonstrated for this ternary periodic structure using ultrashort pulses with an intrinsic conversion efficiency exceedin

Coherent anti-Stokes Raman spectroscopy (CARS) is a powerful tool in combustion diagnostics [1] . It requires three beams, the pump, Stokes and probe beam with at least two different wavelengths. For high pressure applications, the use of fs-pulses i

Starting from a mode-locked femtosecond Yb-laser we generate shot noise limited pulses tunable from 332 nm up to 18,000 nm using a synchronously pumped OPO and cascaded SHG, THG, FHG and DFG generation.

We employed mercury thiogallate (HgGa2S4 or HGS) to achieve the highest average output power from a 1 µm synchronously pumped optical parametric oscillator (SPOPO) generating femtosecond idler pulses continuously tunable in the mid-IR. HGS is one of

We demonstrate the first ZnGeP2-based, femtosecond OPA system driven directly by a Thulium-based fiber-laser system operated at 100 kHz. The OPA delivers mid-to-long-infrared tunable pulses with idler energies up to 2.2 pJ (23% quantum efficiency).
