In this paper a method for identifying the wavelength range of a tunable vertical cavity surface-emitting laser (VCSEL) is introduced. The measuring technology is wavelength modulation spectroscopy (WMS). The laser is tuned over its wavelength by applying a temperature ramp using the onboard Peltier element. During this ramp the 2f absorption lines are recorded. After finishing the temperature ramp and collecting the lines, a ratio-compare algorithm calculates the theoretical amplitudes of selected predefined lines. Then it compares the measured 2f line amplitudes iteratively with the theoretical ones. If the error of the ratios of the calculated and the measured lines is below a predefined limit, the searched lines and hence the emission wavelength are identified.
