Enhanced Two-Photon Absorption in a Hollow-Core Photonic Bandgap Fiber
Enhanced Two-Photon Absorption Hollow-Core Photonic Bandgap Fiber
2010/11/12
We show that two-photon absorption (TPA) in Rubidium atoms can be greatly enhanced by the use of a hollow-core photonic bandgap fiber. We investigate off-resonant, degenerate Doppler-free TPA on the ...

Measurement two-photon absorption cross-section of liquid argon with a time projection chamber
2011/1/6
This paper reports on laser induced multiphoton ionization at 266 nm of liquid Argon in a Time Projection Chamber (LAr TPC) detector. The electron signal produced by the laser beam is a formidable too...

Two-photon Absorption Processes in Semiconductor Quantum Dots
Nonlinear absorption Two-photon absorption Quantum dots
2010/9/29
The two-photon absorption process is a nonlinear phenomenon that shows very low optical efficiency in bulk
semiconductors. For this reason the detection of these processes becomes very difficult from...
Two-Photon Absorption in Size-Quantized Semiconductors with Degenerated Valence Band
Two-Photon Absorption Size-Quantized Semiconductors Degenerated Valence Band
2010/4/15
Two photon absorption in size-quantized films of semiconductors with degenerated band structures are investigated. The carrier energy spectrum and wavefunctions in the bands are calculated using two-b...
