Zutavern, Fred J.; Baca, A.G.; Chow, Weng W.; Hafich, Michael J.; Hjalmarson, Harold P.; Loubriel, Guillermo M.; Mar, Alan M.; O'Malley, Martin W.; Vawter, Gregory A.

A new class of semiconductor laser is presented that does not require p-n junctions. Spectral narrowing, lasing thresholds, beam divergence, temporal narrowing, and energies are shown for these lasers based on current filaments in bulk GaAs.
