Paper Abstract

High power diffraction-limited GaAs/GaAlAs phase-locked laser diode arrays are developed and fabricated by LPE technique, standard photolithographic technique, wet etching and proton bombardment. The tailored gain-guided arrays are carried out by varying width of channel of laser, while the spacing between lasers remains constant. This array consists of six lasers. Its optical output power per facet is 300 mW at 2.7Ith, single mode cw operation, single lobe far-field pattern with FWHM 1.9 degree(s).
