“…Later in an experiment with sodium vapours, Konefal and Ignaciuk [10] showed that the effect is substantially enhanced when use is made of light hydrocarbons (methane, ethane or ethylene) as a buffer gas (efficient generation of radiation requires fast collisional mixing of the upper levels of alkali metal atoms, which is ensured in using molecular buffer gases). Ethane served as a buffer gas in an experiment [11] with a new object, namely, rubidium.…”

We have studied theoretically the operation of a transversely diode-pumped alkali metal vapour laser. For the case of high-intensity laser radiation, we have obtained an analytical solution to a complex system of differential equations describing the laser. This solution allows one to exhaustively determine all the energy characteristics of the laser and to find optimal parameters of the working medium and pump radiation (temperature, buffer gas pressure, and intensity and width of the pump spectrum).

“…[5][6][7][8][9][10][11][12][13]. Numerous theoretical and experimental studies of energy transfer, energy levels mixing, and a three-level lasing in alkalis were performed during that time, [14][15][16][17][18][19][20][21][22][23][24][25][26][27] but an absence of powerful enough narrowband tunable pump laser sources did not allow efficient lasing in alkali vapors until the beginning of the new millennium. The first really efficient lasing in pulsed and continuous wave (CW) operation in Rb and Cs vapors was observed in 2003 to 2005, 28,29 using a Ti:sapphire laser for optical pumping.…”

“…A standard for all alkali lasers, the three-level pump scheme ( Fig. 1) described by Konefal 27 was used to create population inversion on the D1 transition of Rb atoms (795 nm). As a pump source they used a 500-mW Ti:sapphire laser resonant to the rubidium D2 line (780 nm).…”

Abstract. In this review we present an analysis of optically pumped alkali laser research and development from the first proposal in 1958 by Schawlow and Townes to the current state. In spite of the long history, real interest in alkali vapor lasers has appeared in the past decade, after the demonstration of really efficient lasing in Rb and Cs vapors in 2003 and the first successful power scaling experiments. This interest was stimulated by the possibility of using efficient diode lasers for optical pumping of the alkali lasers and by the fact that these lasers can produce a high quality and high power output beam from a single aperture. We present a review of the most important achievements in high power alkali laser research and development, discuss some problems existing in this field, and provide future perspectives in diode pumped alkali laser development.

“…The concept of an optically pumped alkali resonance laser was proposed by Konefal in 1999 [1]. Konefal's proposal was for a longitudinally pumped alkali metal-molecular gas amplifier and was based on his experimental studies of collisionally induced fine-structure mixing in the presence of a molecular buffer gas such as ethane.…”

An optical resonance transition rubidium laser (5 2 P 1/2 →5 2 S 1/2 ) is demonstrated with a hydrocarbon-free buffer gas. Prior demonstrations of alkali resonance transition lasers have used ethane as either the buffer gas or a buffer gas component to promote rapid fine-structure mixing. However, our experience suggests that the alkali vapor reacts with the ethane producing carbon as one of the reaction products. This degrades long term laser reliability. Our recent experimental results with a "clean" helium-only buffer gas system pumped by a Ti:sapphire laser demonstrate all the advantages of the original alkali laser system, but without the reliability issues associated with the use of ethane.
