A method of optimizing the operation point of a laser, including characterizing the laser and controlling the different laser sections by varying the currents injected into the respective laser sections. The method includes sensing discontinuities that occur at mode jumps in a signal by utilizing a detection device that is firmly connected to the laser. Control of the different laser sections is effected by means of a control unit. Different control current combinations and the signal delivered by the detection device are provided to the control unit, which causes the control unit to detect the mode plane of the laser. At least a part of a mode plane, or several mode planes, are stored in a memory connected with the control unit, and the control unit controls the different laser sections so that the laser will operate at the desired operation point. |
