Experimental and theoretical studies of intracavity Raman lasers are presented. Advantages of intracavity Raman lasers, particularly for low-emission cross section and broadly tunable vibronic gain media, are described. Experimental studies of a hydrogen gas Raman laser pumped inside the cavity of an alexandrite laser are presented. A theoretical model

CLEO '97., Summaries of Papers Presented at the Conference on Lasers and Electro-Optics, 2005
In the past, the production of a continuous wave (cw) Raman laser has been limited by the high pump powers needed for the process to proceed with a reasonable gain.

Nonlinear dynamics of Raman lasers
Physical Review A, 1990It has recently been shown that single mode Raman lasers are reducible to a simple mathematical description [1] similar to that of the detuned Haken-Lorenz model but for which operating conditions are considerably relaxed. As such they provide excellent opportunity for quantitative tests of nonlinear dynamics.

Laser Raman scattering applications
Journal of Quantitative Spectroscopy and Radiative Transfer, 1974The advent of laser sources, better optical instruments, and photon counting techniques has put Raman scattering within the range of a number of practical uses. The measurement of densities and temperatures has been demonstrated in numerous laboratory and field situations.

Fiber Raman lasers are broadly tunable optical frequency converters based on stimulated Raman scattering and Raman oscillation in low-loss glass fibers. Their practically and efficiency are based on the long interaction lengths possible in such fibers. Their relative simplicity and wide spectral region of operation make fiber Raman lasers attractive as

Die Raman-Spektroskopie ist seit vielen Jahren eine wichtige Methode zur Untersuchung molekularer Schwingungen. Da die Wirkungsquerschnitte fur die nichtresonante Raman-Streuung jedoch im allgemeinen um mehrere Grosenordnungen kleiner sind als die fur Resonanzfluoreszenz, war vor dem Einsatz von Lasern die geringe Intensitat der Streustrahlung oft der ...

Physics Today, 1977
At present, the low-pressure mercury light source is the most commonly used in Raman spectroscopy. Under normal operating conditions (2.5 kW) it can be calculated that up to 50 W of energy of such a light source is radiated in the 4358 วบ line of the mercury spectrum which is frequently used to excite Raman spectra.

Soviet Journal of Quantum Electronics, 1974
A review is given of the investigations of the properties and characteristics of Raman lasers, i.e., of oscillators and amplifiers using stimulated scattering, and of the associated processes and phenomena. The physical principles and characteristics common to Raman lasers are considered.

IEEE Journal of Selected Topics in Quantum Electronics, 2007
In this paper, we review the developments of crystalline Raman lasers over the past five years. Average powers exceeding 5 W and pulse energies above 1 J in the near infrared have been demonstrated for larger scale devices. There has been a rapid development of all-solid-state sources based on the standard diode-pumped lasers, especially intracavity ...
