Spatial phase fluctuations of the fundamental laser mode caused by spontaneous emission

А. В. Белинский, Anatolii S Chirkin

Published Feb 28, 1989• 0 citations
Publisher

Abstract

A calculation is reported of the degree of spatial coherence of the fundamental radiation mode subject to phase fluctuations in space. It is shown that the degree of spatial coherence (within the beam width) is perturbed only slightly by these fluctuations, compared with subthreshold excitation of higher transverse modes.

The Laser Linewidth – Fairy Tales and Physical Evidence

Markus Pollnau

The laser linewidth manifests the spectral coherence of a lasing resonator mode. It is of fundamental importance, theoretically as much as practically. For more than half a century we have been told that the laser linewidth is a result of quantum fluctuations due to spontaneous emission, which induce amplitude and phase fluctuations, whereas stimulated emission occurs in phase with the incident field. Unfortunately, in such a scenario each emission process would violate the law of energy conservation. We show that a (spontaneous or stimulated) emission process occurs 90 degrees in lead of the incident field, converts one atomic excitation into one photon in the lasing mode and, therefore, conserves the energy, whereas the mentioned fluctuations are the result of vacuum energy and occur at an orders-of-magnitude faster time scale than an emission process.

Influence of spatial coherence of a laser field on the efficiency of two-photon absorption

Tatiana N. Smirnova, Eugene A. Tikhonov

An investigation was made of the dependence of the two-photon absorption of ruby laser radiation in alcohol solutions of rhodamine 6 G on the intensity of the exciting field in the case of single-frequency emission and emission of a large number of transverse modes. The efficiency of the two-photon absorption in the case of multimode excitation was 1.8 times (determined with a relative error of 25 % ) greater than the efficiency of the absorption as a result of single-frequency excitation. The measured absorption coefficient was close to that calculated on the assumption that the single-frequency field was spatially coherent and the spatial fluctuations of the multimode field were described by a Gaussian distribution.

Complex spatiotemporal dynamics in lasers

Jorge R. Tredicce, C. Green, E. J. D’Angelo +1 more

It is well known that transverse intensity profiles of lasers may show a nontrivial spatial structure. Usually, depending on the degree of symmetry, the spatial patterns have been associated with modes of a passive resonator or combinations of them which cause oscillations in the laser intensity (mode beating).1 It was recently shown2 that the fluctuations may be due, instead, to the nonlinear coupling between atoms and the field. Here we show that a spontaneous symmetry-breaking process is also at the origin of the formation of complex spatiotemporal dynamics in which oscillations at a single frequency, quasiperiodicity, and chaos may coexist within in the same spatial structure. We compare our experimental results with those obtained from bifurcation theory and numerical integration of the Maxwell–Bloch equations. The transition from a simple (Gaussian) profile to a complex (turbulent) profile is studied by means of the average intensity patterns, frequencies, and phases of the local intensity and cross-correlation functions.

Atomic motion in resonant fluctuating laser radiation

R. J. Cook

The effect of field fluctuations on the motion of a two-level atom in resonant laser radiation is investigated theoretically. The internal motion of the atom is treated quantum mechanically (optical Bloch equations); the translational motion, which is coupled to the internal motion, is treated classically (Ehrenfest's theorem); and the fluctuating radiation is treated as a classical electromagnetic wave with stochastic phase (phase-diffusion model). An expression for the radiation force and equations of motion for the ensemble-averaged Bloch vector are derived and used to calculate (i) the radiation force in a plane running wave, (ii) the steady-state radiation force in a general standing wave, and (iii) the dissipative force in a plane standing wave in the limit of strong phase fluctuations. In case (iii) it is found that the atomic velocity is damped when the radiation is tuned above resonance, which is opposite to the case of a weak coherent standing wave, in which damping occurs for radiation tuned below resonance. It is shown that fluctuations have a substantial effect on the radiation force only when the spectral width of the radiation approaches or exceeds the spontaneous emission rate.

Quantum noise of multitransverse mode laser fields

Kęstutis Staliūnas, Audrius Berzanskis

Quantum fluctuations in the radiation of multitransverse-mode laser are investigated theoretically and numerically, based on quantum c-number Langevin stochastic equations for the complex amplitudes of transverse modes. It is shown that strong antiphase quantum fluctuations of transverse-mode amplitudes occur, which corresponds to spatial fluctuations of the laser field. Fluctuation spectra are calculated, showing that antiphase fluctuations dominate at low frequencies (smaller than relaxation oscillation frequency), and in-phase oscillations prevail at high frequencies.
