“…However, the present values are among the best ones reported for SSMBE-grown material [8], and further reduction in J th is still to be expected. Other groups have reported threshold current densities well above 1 kA cm −2 for SSMBE-grown visible lasers [9][10][11][12]. Figure 3 shows an example of a light-current curve of a 120 × 600 µm 2 laser with AR/HR ≈ 10/95% coatings, as obtained in the pulsed mode of operation (pulse width of 200 ns at 3 kHz repetition rate) at 20 • C. The laser exhibited the output power of 4.5 W at a 4.3 A drive current and the high slope efficiency of 1.22 W A −1 .…”

High-performance visible (λ ≈ 680 nm) Ga x In 1−x P/(Al y Ga 1−y ) 0.51 In 0.49 P compressively strained single quantum well laser diodes have been grown by solid source molecular beam epitaxy. The waveguide region was designed to have a low Al content in order to enhance the optical field confinement and to improve the material quality. The threshold current density for an infinity long cavity length was estimated to be 150 A cm −2 . The highest external quantum efficiency of 37% per facet was obtained for a cavity length of 480 µm. A characteristic temperature of 130 K was measured in the temperature interval from 20 • C to 50 • C.

“…Such a possibility is foreseeable, as one may judge from the successful results obtained recently for phosphide-based devices grown by SSMBE [6][7][8]. However, reports on SSMBE-grown red lasers are scarce in the literature [9][10][11][12] and their results are inferior to those attainable by MOCVD.…”
