Abstract :
We have shown that we can find the weights and shapes of spatial modes in a semiconductor laser. The 5 μm stripe width laser tested had two lateral spatial modes with approximate power weights of 96% and 4%. We are developing refinements that would be useful for detecting even weaker modes
