Abstract
A laser system has an output/input coupler unit () with a circulator (). An output of the circulator () is operationally connected to a detector unit (). The input/output (EA) of the circulator is operationally connected to a transmitter and a receiver optics. Laser light is input to the circulator (E). The input (E), output (A) and output/input (EA) of the circulator are optical fibers. The pulsed diode () is not temperature stabilized. To reduce amplified spontaneous emission (ASE) generated in the optical fiber amplifier (), a narrow band-pass filter unit () is used. Filter unit () has a central wavelength with a temperature dependence which is matched to the temperature dependent wavelength shift of the pulsed diode ().
