Abstract :
To achieve high power single mode output from an edge emitting semiconductor laser diode, we made an approach to use external cavities to improve the beam quality by providing optical feedback into the laser. By performing both simulation and experiments, we have found out that the external cavity works well to generate single mode laser beams.
