Abstract
A system and method for triggering data acquisition in a semiconductor laser system including outputting electromagnetic energy from the semiconductor laser over a range of wavelengths according to a signaling path. The signaling path includes a plurality of discrete data inputs to the semiconductor laser for outputting electromagnetic energy over a range of wavelengths and the signaling path includes one or more perturbances in transitioning from one wavelength to another wavelength along the signaling path. A series of triggering signals for input to a measurement system is generated by the semiconductor laser. The semiconductor laser also generates a series of valid signal indicators when the outputted electromagnetic energy is not undergoing one or more perturbances. The valid signal indicators may be digitized and stored and/or used to pause the measurement system.
