Narrow Linewidth near-UV InGaN Laser Diode based on External Cavity Fiber Bragg Grating
Antoine Congar, Mathilde Gay, Georges Perin +8
We realize a fiber Bragg grating InGaN based laser diode emitting at 400 nm and demonstrate its high coherency. Thanks to the fabrication of a narrow band fiber Bragg grating in th…

Intracavity Brillouin gain characterization based on cavity ringdown spectroscopy
Ananthu Sebastian, Stéphane Trebaol, Pascal Besnard
We report a technique based upon the cavity ringdown method that enables to characterize the Brillouin gain coefficient directly in a laser cavity. Material gain, optical cavity pa…
