A simple wavelength chirping formula is presented which includes small nonlinearities in the net gain such as spectral hole burning. The two dominant terms are a laser-structure-independent derivative or]] transient" chirp and a structure-dependent]] adiabatic" chirp, each with distinctly different lightwave system consequences. The two chirp contributions are indirectly related through their mutual association with relaxation oscillations. Time-resolved spectral measurements on a number of different laser structures support the results.
