So as to establish laser light with a desirec characteristic downstream a laser light source (151), the light is amplified by an amplifier (107) which is gain-modulated (E107G).
Laser light (.lambda.L) within a spectrum range is generated (51g) and filtered (29g). Thereby the spectral location of the filter characteristic (.lambda.F) is shifted in a controlled manner (60) to establish a desired characteristic of output laser light as for considering a temperature depended shift (.DELTA.Ñ) of the spectrum range generated by the laser source (51g).
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).
