Abstract

Higher-power diode lasers are essential to new optical systems such as erasable disks. A window structure laser,¹ which has a crescent active region in its gain region and a flat one in the vicinity of its facets (windows), seems suitable for such use. However, this structure was proved to have transverse mode instability,² This instability is caused by optical mismatching between the window and gain region. We present an improved window structure, which is characterized by its high-power operation, stable transverse mode, and high reliability.
