Abstract
We have recently produced pulses with temporal durations of from 0.7 to several picoseconds from optically pumped GaAs lasers.1 These lasers have operated in a variety of single wavelengths over a broad spectral region between 0.77 µm and 0.90 µm.2 We now report extension of this work to the In1−x GaxAsyP1−y, quaternary system, including the end-points, InP and In0.53Ga0.47As. With only five values of (x,y) we have observed lasers operating at various single wavelengths spanning the range between 0.83 µm (InP) and 1.59 µm (In0.53Ga0.47As).
