Room-temperature low-current-threshold broad-area Fabry-Perot Al/sub x/Ga/sub 1-x/As/Al/sub y/Ga/sub 1-y/ As double-heterostructure (DH) lasers have been prepared by molecular-beam epitaxy (MBE) covering the lasing emission wavelength from 8900 to 7200 A (infrared to visible). In this emission range, the averaged pulsed current threshold densities J/sub th/ are as low as those obtained by liquid-phase epitaxy (LPE). At approx.8200 A, the wavelength at which DH lasers have also been prepared by metalorganic chemical-vapor deposition (MO-CVD), the J/sub th/ 's of the MBE grown lasers are lower.
