Abstract :
Experimental results are presented for ultrashort optical pulse generation by an AlGaAs tandem-type laser with transverse junction stripe structure. The shortest optical pulse width of 14 ps was observed by an ultrafast streak camera, while typical pulse widths were about 20 ps. Further shorter pulses may be expected with this type of semiconductor laser by adequate control of the saturable absorber region.
