Injection laser stabilization
Patent
·
OSTI ID:5853646
The apparatus for stabilizing the output characteristics of an injection laser has a device for producing an electrical pulse train representative of an optical pulse train of the laser. The electrical pulse train is fed to circuitry which monitors the switch-on delay of the laser and controls the bias current of the laser such that the switch-on delay is maintained constant. Alternatively the pulse length can be monitored. The pulse amplitude or mean pulse energy can also be monitored and maintained constant.
