Gain and threshold in noninversion lasers

Abstract

The influence of the atomic lifetime and Raman field strength on the gain and laser threshold in noninverted atomic systems is studied. Results show that to achieve useful gain in such a system, it is necessary to use a sufficiently intense Raman field, atoms with a long lifetime for the lower active levels, and a small cavity loss.

Role of atomic coherence in lasing without inversion

Zhenfei Luo, Zhizhan Xu

A noninversion laser system which is closed lifetime broadened and free of the restriction on atomic decay rates is proposed. For the realization of lasing without inversion, the Rabi frequency of the applied field must exceed a lower threshold. Moreover, the coherence term in dressed states must enhance the gain. These results are obtained beyond the specific approximations.

Quantum Noise Reduction in Raman Lasers

Helmut Ritsch, Monika A. M. Marte, P. Zoller

We demonstrate that the intensity fluctuations of a laser with a Raman gain medium, described by a large number of independent 3-level atoms, can drop well below the shot noise level. In the limit of a good cavity, where one can adiabatically eliminate the atoms, we find an optimum Mandel Q parameter of Q ≈ −1/2 over a large range of parameters, when the laser is operated well above threshold. This leads to a strong suppression of the low-frequency quantum fluctuations in the laser output. In addition we find that due to suppression of spontaneous emission into the lasing mode, the spectral linewidth of the emitted light can be reduced below the Schawlow-Townes limit by more than one order of magnitude.

Laser Model in the High-Q Limit

Z. Ficek, Mohamed Ridza Wahiddin

In this chapter, we turn our considerations to the simplest model of a laser that includes all the essential features of any practical laser. The one-photon losses (due to coupling to the environment), linear gain (due to inverted atoms) and saturation (due to nonlinear loss), that are experienced by a single-mode (laser) cavity are all included in the calculations and their role in the laser properties is fully explored.We point out that all lasersmust have these three elements to operate as a laser. If there is only a linear gain, then of course there can be no output, since an output causes a loss. With both gain and loss, but not saturation, the laser intensity is either near zero (well below threshold), or else it rises infinitely (well above threshold). Neither case is very useful as a model of a real laser, which has a finite output above threshold. This is why a saturation mechanism is needed, such as an intensity dependent nonlinear loss. This simple model used here is then obtainable in the limit of a high-Q laser operating not too far above threshold.

Nonlinear theory of noninversion lasers of an open three-level system

Shi-Yao Zhu, De-Zhong Wang, Jin-Yue Gao

A nonlinear theory of a noninversion laser of an open three-level system based on electromagnetically induced transparency is given. In this noninversion laser model, a nonselective pumping mechanism is used for obtaining lasing gain such that the population in the lower lasing level is always larger than a half of the total population no matter whether the driving field is on or off. In the lasing region, there is no direct pumping to the upper level. The conditions for the existence of a nontrivial and stable laser field are obtained. The dependence of the laser intensity on the intensity of the driving field and the ratio of the two decay rates from the upper level has been obtained, and the ways to obtain a large laser field have been studied.

Photon noise reduction in lasers

Fritz Haake, S. M. Tan, Daniel F. Walls

We consider the problem of reducing the contributions of pump and spontaneous-emission noise to the output noise of a laser field. We consider two models based on an atomic medium, one analytic, the other involving numerical simulation of a sequence of pump cycles. The predictions of both models are shown to agree. For regular pump excitation the intensity fluctuations of a laser well above threshold may be reduced to zero at the cavity resonance frequency if the ratio of the lifetimes of the upper and lower lasing levels is sufficiently large that spontaneous emission is suppressed. When the atomic lifetimes are comparable, spontaneous emission reduces the amount of noise reduction. For example, for equal atomic lifetimes regular pump excitation will result in a maximum noise reduction in the output field of one-half the shot-noise limit.

Detuning enhanced intracavity photon number stabilization in Raman lasers

K. J. Schernthanner, Helmut Ritsch

Detuning the laser and the pump light from the atomic transitions in a three-level Raman laser can lead to a strong stabilization of the intracavity photon number. The corresponding Mandel Q parameter attains highly non-classical values very close to its optimum of Q=-1 and thus is significantly smaller than for the resonant case or the regularly pumped laser Q>- 1/2 . Subsequently we show that inhomogeneous Doppler broadening of the atomic lines does not drastically influence the non-classical behaviour of the intracavity field as long as the laser is operated sufficiently far above threshold.
