Abstract (en)

[origin: WO2007138013A1] This application concerns a laser source comprising a principal self-adaptive laser cavity comprising at least a principal gain medium (MA1) set about a principal direction and several mirror (HR) permitting the creation of a gain hologram in the center of the above mentioned principal gain medium by interference of a first optical wave (A1) set about the principal direction and a second optical wave (A3) set about a direction different from the principal direction, the waves being generated by the principal gain medium whose main feature is that it comprises a secondary laser source (SLs) delivering photons at a frequency which these impose on the principal cavity as well as the means for inserting the said photons in the center of the cavity of the principal laser.
