Title
(EN) SINGLE LONGITUDINAL MODE RING RAMAN LASER
(FR) LASER RAMAN EN ANNEAU À MODE LONGITUDINAL UNIQUE
Abstract
(EN) A single longitudinal mode ring Raman laser including: a pump source outputting a pump light power, resonantly coupled to a first ring resonator; a optical measurement and piezo-actuator for stabilising the resonant coupling of the pump light power to a first ring resonator; a first ring resonator including a Raman gain medium, wherein the Raman gain medium receives the pump light power and undergoes Raman lasing generating resonated Stokes power at the corresponding Stokes output wavelength; the first ring resonator acting as a feedback loop for the pump light power and the resonated Stokes power and outputting a portion of the Stokes power as the laser output.
(FR) L'invention concerne un laser Raman en anneau à mode longitudinal unique qui comprend : une source de pompage émettant une puissance de lumière de pompage, couplée en résonance à un premier résonateur en anneau; une mesure optique et un actionneur piézoélectrique pour stabiliser le couplage résonant de la puissance de lumière de pompage à un premier résonateur en anneau; un premier résonateur en anneau comprenant un milieu de gain Raman, le milieu de gain Raman recevant la puissance de lumière de pompage et subissant une émission laser Raman générant une puissance de Stokes à résonance à la longueur d'onde de sortie de Stokes correspondante; le premier résonateur en anneau faisant office de boucle de rétroaction pour la puissance de la lumière de pompage et la puissance de Stokes à résonance et délivrant en sortie une partie de la puissance de Stokes en tant que sortie laser.
