Stimulated emission in optically pumped ZnSe is reported. The emission at 4580 Å is observed at temperatures up to 250 K in solution grown ZnSe crystals with improved near band edge luminescence.

GaAs deep-center stimulated-emission at 1.5µm
2010 Edition, May 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

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...

Fast Gate Synchronized Subharmonic Modulation in Stimulated Emission Microscopy
2019 Edition, September 1, 2019 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, an alternative modulation technique working at much higher frequency (38 MHz) is demonstrated for stimulated emission microscopy. In this way, shot noise limited sensitivity and high speed imaging can be achieved.

Stimulated emission depletion with sub-ns pulses
2003 Edition, January 1, 2003 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

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...

Monolithic microresonator for simultaneous lasing feedback and intracavity hyperparametric oscillation
2015 Edition, May 1, 2015 - Optical Society (The) (OSA)

We demonstrate simultaneous lasing and parametric oscillation with high-Q (> 1010) MgF2 monolithic microresonators. Stable lasing around 698nm is achieved with sub-25kHz linewidth and 8.8nm tuning range. Multi-pair hyperparametric oscillation is observed over 137...

Hybrid photonic-plasmonic resonances to control spontaneous and stimulated emission
2017 Edition, June 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

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...

Far and Mid IR Stimulated Emission in HgCdTe QW Heterostructures
2019 Edition, September 1, 2019 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Stimulated emission (SE) at wavelengths up to 24 μm (12.5 THz) and down to 2.8 μm is demonstrated from HgCdTe quantum well (QW) heterostructures. Non-radiative Auger recombination is show to be mitigated due to relativistic energy spectrum. Pump-probe carrier...

Transient THz stimulated emission from silicon pumped by FELs
2017 Edition, August 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

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...

Stimulated emission on sodium D-lines using broadband optical pumping
2017 Edition, June 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

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 ....
