Development of an ultra short wavelength solid state laser

Abstract

Laser emission in the ultra short wavelength region from solid-state crystals may be possible as demonstrated through a rigorous quantum optic method. It appears that Zeeman’s effect in a deformed crystal lattice has a determinant role in contributing to the conditions of gain enhancement. We found the same conditions of gain enhancement assuming the crystal in Electromagnetic Transparency (EIT) conditions. It has been already demonstrated that Lasing Without Inversion (LWI) can be obtained at EIT conditions. The paper revises the above demonstrations and discusses the possibility of realizing a solid-state laser emitting in the ultra short wavelength region.

Progress in ultra short wavelength solid state laser

M. M. S. Gualini

We demonstrated through a rigorous quantum optic method the possibility of obtaining laser emission in the ultra short wavelength region from solid state crystals. We related the results to the Zeeman’s effect in a crystal lattice and found that Electromagnetic Transparency (EIT) may be attained through this effect leading to a condition of Lasing Without Inversion (LWI). The paper gives a detailed mathematical model of the laser and proposes some simulation results.

Progress in developing an ultra short wavelength solid state laser

M. M. S. Gualini

We demonstrated through a rigorous quantum optic method the possibility to obtain extremely short wavelengths in solid-state deformed crystals hinting that the Zeeman’s effect in a crystal lattice has an essential role in contributing to the conditions of gain enhancement. We found the same conditions of gain enhancement assuming the crystal in Electro Magnetic Transparency (EIT) conditions thus suggesting that Zeeman’s effect in crystals and EIT are somehow linked together. The paper presents the first attempt to relate the crystal deformation parameters to the Rabi’s frequencies, thus confirming rigorously the link between Zeeman’s effect and EIT.

Advancement in very-short-wavelength emission in solid state lasers

M. M. S. Gualini

Solid state lasers emitting at very short wavelengths (>10nm) are very attractive for several applications in material proce3ssing and holography, but not yet demonstrated. Physical limitations prevent using classic laser schemes. We present a semi-empirical and rigorous demonstration of the feasability of a solid state x-ray laser and find some relations of the suggested scheme with EIT (Electro-Magnetic Induced Transparency) and Lasing Without Inversion (LWI).

Suppression of excited-state absorption: A path to ultraviolet tunable solid-state lasers

Elena Kuznetsova, Roman L. Kolesov, Olga A. Kocharovskaya

A method of suppression of losses due to excited-state absorption (ESA) in laser crystals is proposed, based on the well-known phenomenon of electromagnetically induced transparency. Typical situations in which ESA prevents lasing are considered. Theoretical analysis shows that by using an additional driving laser field one can inhibit ESA and make lasing possible. On the basis of available spectroscopic information estimates for rare-earth-ion-doped laser materials are presented. They show the feasibility of obtaining optical gain at parity-allowed $4{f}^{n}\ensuremath{\leftrightarrow}4{f}^{n\ensuremath{-}1}5d$ transitions of rare-earth ions in the ultraviolet spectral region after suppression of ESA at an emission wavelength into the conduction band of a host material.

Demonstration of lasers without inversion

Marlan O. Scully, Leo W. Hollberg, Mikhail D. Lukin +1 more

Summary form only given. Intensive theoretical work, carried out in the past decade, has indicated that optical properties of matter can be dramatically affected by atomic coherence and interference effects. In particular, atomic coherence and interference was shown to lead to such intriguing phenomena as electromagnetically induced transparency, lasing without population inversion (LWI), and resonant enhancement of refractive index accompanied by vanishing absorption. In the present paper we report the first experimental observation of LWI oscillation and the first demonstration of index enhancement.

Láseres sin inversión de población

J. Mompart, V. Ahufinger, R. Corbalán

The most commonly used lasers operate with population inversion. This requires an incoherent pumping power (from lamps, electrical discharges, etc.) that rapidly scales with the frequency of the generated laser radiation. In practice, this is the main obstacle for the operation in the continuous-wave regime of short-wavelength lasers in the UV, X-rays, etc. But lasers can also operate without population inversion using atomic coherences excited in the laser medium by coherent pumping with another laser. We present in this paper a short review of the field of lasing without inversion (LWI). In particular, we summarize the basic physics of LWI in the framework of both semiclassical theory and quantumjump formalism to describe light-matter interaction. We also review the experimental state-of-the-art in LWI. Most proof-of-principle demonstrations of LWI have used atomic vapours, so far. But recently gain without inversion (a pre-requisite for lasing) has been observed also in a technologically relevant medium: semiconductor nanostructures that can be tailored to have “artificial atom” electron states.
