Stimulation Emission Depleted Photoacoustic
Optics Express, 2019 We demonstrate that the Stimulated Emission Depletion (STED) concept, which is usually invoked for fluorescence, can be extended to photoacoustic effects. When two-nanosecond pulses of exciting and stimulating light are synchronized, 80% of the acoustic signal generated through excited state absorption (ESA) can be quenched.

Optical Gain in Semiconducting Polymer Nano and Mesoparticles
Molecules, 2021 The presence of excited-states and charge-separated species was identified through UV and visible laser pump and visible/near-infrared probe femtosecond transient absorption spectroscopy in spin coated films of poly[N-9″-heptadecanyl-2,7-carbazole-alt-5 ...

Understanding High-Gain Twin-Beam Sources Using Cascaded Stimulated Emission
Physical Review X, 2020 We present a new method for the spectral characterization of pulsed twin-beam sources in the high-gain regime, using cascaded stimulated emission. We show an implementation of this method for a periodically poled potassium titanyl phosphate spontaneous ...

Stimulated Emission Cross Section in Xenon-Neon Lasers
مجلة بغداد للعلوم, 2017 Gas Lasers are important tools that are used in variety purposes, for their low and (cw) output power. The aim of this study was to prepare a way to calculate an optimum stimulated emission cross-section in a gas laser containing a mixture of Xenon and ...

Stimulated parametric emission microscopy
Optics Express, 2006 We propose a novel microscopy technique based on the four-wave mixing (FWM) process that is enhanced by two-photon electronic resonance induced by a pump pulse along with stimulated emission induced by a dump pulse. A Ti:sapphire laser and an optical parametric oscillator are used as light sources for the pump and dump pulses, respectively.

Quantum-enhanced stimulated emission detection for label-free microscopy
, 2020 Nonlinear optical microscopy techniques have emerged as a set of successful tools for biological imaging. Stimulated emission microscopy belongs to a small subset of pump-probe techniques, which can image non-fluorescent samples without requiring ...

Stimulated emission from nitrogen-vacancy centres in diamond
Nature Communications, 2017 Here Jeskeet al. show both theoretical and experimental evidence for stimulated emission from negatively charged nitrogen vacancy centres using light in the phonon sidebands around 700 nm, demonstrating its suitability as a laser medium.

EUV stimulated emission from MgO pumped by FEL pulses
Structural Dynamics, 2017 Stimulated emission is a fundamental process in nature that deserves to be investigated and understood in the extreme ultra-violet (EUV) and x-ray regimes.
