A laser system comprises a master-oscillator/power-amplifier (51) whereby the master-oscillator comprises a pulsed diode (3) and a pumped active optical fibre power-amplifier (9). Substantially all guides of laser light (5, 9, 31, 29, 33, 25, 35, 39, 45) are optical fibres. The pulsed diode (3) is not temperature stabilized. To reduce nevertheless ASE generated in the optical fibre amplifier (9), a narrow band-pass filter unit (29) is used. Filter unit (29) has a central wavelength with a temperature dependence which is matched to the temperature dependent wavelength shift of the pulsed diode (3).

Système laser comprenant un oscillateur pilote/amplificateur de puissance (51), cet oscillateur pilote étant composé d'une diode pulsée (3) et d'un amplificateur de puissance (9) possédant une fibre optique active pompée. Pratiquement la totalité des guides de lumière laser (5, 9, 31, 29, 33, 25, 35, 39, 45) consistent en des fibres optiques.
