Nonlinear dispersion of avalanche upconversion.

چکیده
Two-beam coupling measurements of an avalanche upconversion transition in concentrated Tm:LiYF (4) confirm that, despite the resonant nature of the excited-state optical interaction, the induced response is strongly dispersive. This surprising characteristic is shown to be a general feature of avalanche polarization, with an off-resonant process dominating the resonant response.

Avalanche upconversion in Tm:YALO(3).
We report the sudden appearance of upconversion fluorescence and resonant increasing absorption above a threshold intensity in Tm:YALO 3 at room temperature. These effects are shown to arise from nonlinear, cooperative , excited-state dynamics. Comparison with quantum theory reveals essential roles both for pairwise cross relaxation and excitation migration among Tm impurity ions. Absorption fe...
متن کاملUpconversion Laser Processes
Pump processes that produce upconversion laser emission in trivalent rare earth ion-doped gain media are described, and the performance of upconversion lasers pumped by these processes is reviewed. Sequential two-photon absorption upconversion, cooperative energy transfer upconversion and photon avalanche upconversion are discussed in relation to the production of visible laser emission. Using ...

The first laser to operate with an output wavelength shorter than that of the excitation was a pulsed erbium laser reported by Johnson and Guggenheim.l Since this early work, a variety of continuous-wave lasers have been reported in which upconversion occurs by different mechanisms, and inversions of upconverted energy levels have been sustained by avalanche processes, 2.3 direct pairpumping,4 ...
متن کاملEnergy Transfer Upconversion
The usual fluorescence behavior follows Stokes law, where exciting photons are of higher energy than emitted photons. Anti-Stokes processes usually concern emitted energies in excess of excited energies by only a few kT. These processes include anti-Stokes emission by the thermal bands or by the Raman effect. There are processes, however, in which emission photon energy exceeds excited photon e...
متن کاملNonradiative dynamics of avalanche upconversion in Tm:LiYF4
In this paper we examine nonradiative processes ~cross relaxation and energy migration! vital for the generation of blue avalanche emission in Tm:LiYF4 crystals subjected to radiation near 648 nm. Time-domain and temperature-dependent measurements indicate that two sequential cross-relaxation processes dominate the nonradiative decays of the G4 and H4 excited states in this crystal. The occurre...
