PCT No. OCT/FR88/00100 Sec. 371 Date Oct. 20, 1988 Sec. 102(e) Date Oct. 20, 1988 PCT Filed Feb. 23, 1988 PCT Pub. No. WO88/06811 PCT Pub. Date Sep. 7, 1988.The laser generator includes a device for phase-locking the mode of the laser generator, the device being placed between the amplifying active medium (3) and the rear reflecting mirror (1) and comprising, firstly a non-dispersive non-linear medium (5) placed in contact with said rear mirror (1), and secondly means (11 to 16) for transforming a Gaussian beam having circular symmetry coming from the amplifying medium into a beam whose morphology is adapted to soliton propagation in said non-linear medium (5). The invention avoids the use of acousto-optical type modulators and may be applied to a very wide range of wavelengths.
