FIG. 3.

Time-averaged near-field beam profiles for different external mirror lengths at bias injection currents of (a)–(c) 1.1Ith and (d)–(g) 1.5Ith . Beam profiles for (a) solitary laser, (b) Lext  = 7 cm, and (c) Lext  = 20 cm at 1.1Ith and an external mirror reflectivity of 10%. Beam profiles for (d) solitary laser, (e) Lext  = 6 cm, (f) Lext  = 8 cm, and (g)Lext  = 17 cm at 1.5Ith and an external mirror reflectivity of 20%.
