Abstract
A laser-system comprises master-oscillator/power-amplifier (51) whereby the master-oscillator comprises a pulsed diode (3) and a pumped active optical fiber power-amplifier (9). Substantially all guides of laser light (5, 9, 31, 29, 33, 25, 35, 39, 45) are optical fibers. The pulsed diode (3) is not temperature stabilized. To reduce nevertheless amplified spontaneous emission generated in the optical fiber 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).
