Room-temperature stimulated-emission, optical gains larger than known significant losses, and single-pass laser action from GaAs deep-centers are demonstrated at low electrical injection in cw mode at 1.3-1.5µm. Fast hole capture maintains the...
We have designed a new stimulated emission depletion microscope that applies longer STED pulses (>100 ps) than commonly used (5-10 ps). It is found that longer pulses have a positive effect on photostability of the fluorescent molecules. Utilizing ultrafast shutters, the recovery of...
By hybridizing plasmonic and photonic resonators one can realize narrow bandwidth structures with plasmonic-like field enhancements. I will present our progress in understanding the hybridization physics and realizing control of spontaneous and stimulated...
Transient-type stimulated emission in the terahertz frequency range has been achieved from silicon crystals doped by phosphorus and bismuth donors under optical excitation by a few picosecond-long pulses generated by the infrared free electron lasers, FELIX...
This paper considers the issue how to obtain the amplification of stimulated emission in the cell with sodium vapor using a longitudinally pumped dye laser arrangement at a line shorter than the transitions from the ground state to the levels D 1 and D 2 ....
We show that the stimulated emission of surface plasmon polaritons on top of lamellar metal/dielectric metamaterial has much lower threshold than on top of silver.
High-field domains passing through n -type gallium arsenide pulsed above a critical field produce electron-hole pairs by impact ionization, resulting in emission of recombination radiation of band gap energy. Specimens have been made in a configuration that allows intense...
The stimulated emission threshold of SPPs can be reduced by an order of magnitude if the operation range is changed from visible to near-IR and metamaterial substrates are used instead of silver films.
Plasmon stimulated emission gives rise to coherent emission of leakage radiation from adjacent stripes in arrays of bi-metallic structures coated with dye-doped dielectric. This resulted in unambiguous interference patterns imaged by Fourier-plane leakage...
